WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

The Hurricane Warning from High Island to Intracoastal City has
been replaced with a Tropical Storm Warning.


SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
* High Island Texas to the Mouth of the Mississippi River

A Tropical Storm Warning is in effect for...
* High Island Texas to the Mouth of the Mississippi River

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline in
the indicated locations. For a depiction of areas at risk, please
see the National Weather Service Storm Surge Watch/Warning Graphic,
available at hurricanes.gov. This is a life-threatening situation.
Persons located within these areas should take all necessary
actions to protect life and property from rising water and the
potential for other dangerous conditions. Promptly follow
evacuation and other instructions from local officials.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 700 AM CDT (1200 UTC), the center of Hurricane Laura was located
near latitude 31.2 North, longitude 93.3 West. Laura is moving
toward the north near 15 mph (24 km/h) and this motion should
continue through the day. A northeastward to east-northeastward
motion is expected tonight and Friday. On the forecast track, Laura
will move northward across western and northern Louisiana
through this afternoon. The center of Laura is forecast to move
over Arkansas tonight, the mid-Mississippi Valley on Friday, and
the mid-Atlantic states on Saturday.

Maximum sustained winds are near 100 mph (160 km/h) with higher
gusts. Rapid weakening is forecast, and Laura is expected to
become a tropical storm later today.

Hurricane-force winds extend outward up to 60 miles (95 km) from
the center and tropical-storm-force winds extend outward up to 175
miles (280 km). An observing site in Alexandria, Louisiana,
recently reported a wind gust to 74 mph (119 km/h)

The estimated minimum central pressure is 970 mb (28.64 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Laura can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Johnson Bayou to Rockefeller Wildlife Refuge including Calcasieu
Lake...15-20 ft
Rockefeller Wildlife Refuge to Intracoastal City...10-15 ft
Intracoastal City to Morgan City including Vermilion Bay...8-12 ft
Sea Rim State Park to Johnson Bayou including Sabine Lake...4-8 ft
Morgan City to Mouth of the Mississippi River...4-7 ft
High Island to Sea Rim State Park...2-4 ft
Mouth of the Mississippi River to Ocean Springs including Lake
Borgne...1-3 ft
Lake Pontchartrain and Lake Maurepas...1-3 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location, where the surge will be
accompanied by large and destructive waves.

Life-threatening storm surge with large and destructive waves will
continue within the Storm Surge Warning area this morning. This
surge could penetrate up to 40 miles inland from the immediate
coastline, and flood waters will not fully recede for several days
after the storm.

Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.

WIND: Hurricane-force winds and damaging wind gusts are also
expected to spread well inland into portions of eastern Texas and
western Louisiana this morning. Tropical storm conditions will
spread northward within the warning areas through the day.

RAINFALL: Through Friday, Laura is expected to produce the following
rainfall totals:

Across portions of Louisiana, Mississippi, across Arkansas: 6 to 12
inches with isolated totals of 18 inches.

This rainfall will cause widespread flash and urban flooding, small
streams and creeks to overflow their banks, and minor to moderate
freshwater river flooding.

Through Saturday, Laura is expected to produce 1 to 3 inches with
isolated maximum amounts of 5 inches across the mid-Mississippi
Valley and portions of the Tennessee and Lower Ohio Valley, the
central Appalachians and the Mid-Atlantic States.

This rainfall may lead to flash and urban flooding and rapid rises
on small streams.

TORNADOES: Tornadoes are possible today and tonight over parts of
Louisiana, Arkansas, and western Mississippi.

SURF: Swells produced by Laura are affecting the U.S. Gulf coast
from the west coast of Florida to Texas and northeastern Mexico.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local
weather office.

HAZARDS AFFECTING LAND
----------------------
Key messages for Laura can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

STORM SURGE: Water levels remain elevated along the Gulf Coast
and will continue to subside over the next few hours.

WIND: Damaging wind gusts and tropical storm conditions are
expected to spread into portions of northern Louisiana and Arkansas
through this evening.

RAINFALL: Through Friday Laura is expected to produce additional
rainfall totals of 4 to 8 inches across portions of Louisiana,
Mississippi and Arkansas, with isolated storm totals of 18 inches
over Louisiana.

This rainfall will continue to cause widespread flash and urban
flooding, small streams and creeks to overflow their banks, and
minor to moderate freshwater river flooding.

Through Saturday, Laura is expected to produce 1 to 3 inches with
isolated maximum amounts of 5 inches across the mid-Mississippi
Valley, portions of the Tennessee and Lower Ohio Valleys, the
central Appalachians, and the Mid-Atlantic States.

This rainfall may lead to flash and urban flooding and rapid rises
on small streams.

TORNADOES: Tornadoes are possible through tonight over parts of
Louisiana, Arkansas, and western Mississippi. The risk for tornadoes
will shift into the Mid-South and Tennessee Valley regions on Friday
into Friday night.

SURF: Swells produced by Laura continue to affect the U.S. Gulf
coast from the Florida Panhandle to Texas and northeastern Mexico.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local

Hurricane Laura Discussion Number 31
NWS National Hurricane Center Miami FL AL132020
1000 AM CDT Thu Aug 27 2020

Laura has continued to move inland over west-central Louisiana this
morning. Satellite and radar imagery has shown a gradual filling of
the eye, and a reduction in Doppler velocities in the northeastern
eyewall. The initial intensity is set at 65 kt, based on a reduction
of the Doppler velocities and the typical filling rate of inland
hurricanes. The highest wind gusts at official observing sites
within the past few hours has been at Alexandria, Louisiana, where a
gust to 75 kt has been reported.

The hurricane is moving slightly east of due north or 005/14 kt. A
general northward motion should continue through this evening as the
hurricane moves around the western portion of a mid-level ridge over
the southeastern United States. Laura should turn northeastward
overnight while it moves across Arkansas and becomes embedded within
the mid-latitude westerlies. A faster east-northeastward motion is
forecast by late Friday, which will bring Laura or its remnants
across the central Appalachians and to the Mid-Atlantic states on
Saturday. After that time, the system is expected to accelerate
east-northeastward to northeastward over the western Atlantic.

Laura will continue to rapidly weaken today while it moves farther
inland. The cyclone will become a tropical storm this afternoon and
is expected to weaken to a tropical depression tonight or early
Friday. Although Laura is weakening, strong wind gusts are likely
to spread over northern Louisiana and Arkansas into this evening.
The UKMET and ECMWF models continue show the extratropical remnants
of Laura strengthening somewhat over the western Atlantic, and the
NHC forecast continues to depict the system as a gale-force low at
days 3-5. An alternate scenario is for the system to be absorbed
by a frontal boundary over the western Atlantic before the end of
the forecast period. The extratropical portion of the forecast is
based on guidance from the NOAA Ocean Prediction Center.

Key Messages:

1. Dangerous storm surge will result in elevated water levels for
the next few hours along the Gulf Coast from Sabine Pass, Texas, to
Port Fourchon, Louisiana. In some areas where surge penetrated far
inland, flood waters will not fully recede for several days.

2. Damaging winds will continue near the center of Laura over
portions of northern Louisiana and Arkansas today and this evening.

3. Widespread flash flooding along small streams, urban areas, and
roadways will continue across portions of Louisiana, Mississippi,
and Arkansas. Additional rainfall will also lead to minor to
moderate freshwater river flooding. The heavy rainfall threat and
flash and urban flooding potential will spread northeastward into
the middle-Mississippi, lower Ohio and Tennessee Valleys, and
Mid-Atlantic States Friday and Saturday.

Tropical Storm Laura Discussion Number 32
NWS National Hurricane Center Miami FL AL132020
400 PM CDT Thu Aug 27 2020

Laura has continued to weaken this afternoon. The satellite and
radar presentation of the tropical cyclone has continued to degrade,
and the center has now moved into southern Arkansas. The initial
intensity has been reduced to 45 kt, and is based on a blend of
surface observations, Doppler radar data, and typical over land
tropical cyclone filling rates. Sustained tropical storm force
winds have been observed in northern Louisiana, and wind gusts to
nearly 50 kt were reported in southern Arkansas earlier this
afternoon.

Laura will continue to rapidly weaken during the next 6-12 hours,
and it is expected to become a tropical depression either this
evening or overnight. The extratropical remnants could strengthen
over the western Atlantic early next week, and the track and
intensity forecast for that time is based on guidance from
the NOAA Ocean Prediction Center.

The tropical storm has turned north-northeastward or 015/13 kt.
The cyclone is forecast to turn northeastward, and then east-
northeastward as it becomes embedded within the mid-latitude
westerlies on Friday. This motion will take Laura or its remnants
across the central Appalachians and to the Mid-Atlantic states on
Saturday. After that time, the system should accelerate
east-northeastward to northeastward over the western Atlantic. The
updated NHC track forecast remains similar to the previous advisory
and is close to the various consensus models.

Key Messages:

1. Tropical storm force winds, especially in gusts, will continue
near the center of Laura over portions of extreme northern Louisiana
and Arkansas this evening.

2. Flash flooding along small streams, urban areas, and roadways
will continue across portions of Louisiana, Mississippi and
Arkansas. Additional rainfall will also lead to minor to moderate
freshwater river flooding. The heavy rainfall threat and flash and

BULLETIN
Tropical Depression Laura Advisory Number 33
NWS National Hurricane Center Miami FL AL132020
1000 PM CDT Thu Aug 27 2020

...LAURA WEAKENS TO A DEPRESSION OVER ARKANSAS...
...FLOOD THREAT CONTINUES...


SUMMARY OF 1000 PM CDT...0300 UTC...INFORMATION
-----------------------------------------------
LOCATION...35.1N 92.0W
ABOUT 30 MI...50 KM NNE OF LITTLE ROCK ARKANSAS
MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H
PRESENT MOVEMENT...NNE OR 15 DEGREES AT 15 MPH...24 KM/H
MINIMUM CENTRAL PRESSURE...993 MB...29.33 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1000 PM CDT (0300 UTC), the center of Tropical Depression Laura
was located near latitude 35.1 North, longitude 92.0 West. The
depression is moving toward the north-northeast near 15 mph (24
km/h), and this general motion should continue overnight.
A northeastward to east-northeastward motion is expected to begin on
Friday and continue into Saturday. On the forecast track, the
center of Laura is forecast to move over Arkansas tonight, the
mid-Mississippi Valley on Friday, the mid-Atlantic states on
Saturday, and over the western Atlantic on Sunday.

Maximum sustained winds have decreased to near 35 mph (55 km/h)
with higher gusts. Laura is expected to become a remnant low
pressure system on Saturday, and an extratropical low later this
weekend.

The estimated minimum central pressure is 993 mb (29.33 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Laura can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

RAINFALL: Through Friday, Laura is expected to produce the
following additional rainfall totals:

Over central and northern Arkansas: Additional 3 to 6 inches.

Over southern Louisiana and southern Mississippi: 1 to 3 inches,
with isolated additional totals of 5 inches.

Over northern Mississippi, western Tennessee, and south-central to
southeast Missouri: 1 to 3 inches, with isolated totals of 5
inches.

This rainfall will continue to cause widespread flash and urban
flooding, small streams and creeks to overflow their banks, and
minor to moderate freshwater river flooding.

Through Saturday, Laura is expected to produce 1 to 3 inches with
isolated maximum amounts of 5 inches across portions of the
Tennessee and Lower Ohio Valleys, the central and southern
Appalachians, and the Mid-Atlantic States. This rainfall may lead to
flash and urban flooding and rapid rises on small streams.

TORNADOES: A few tornadoes remain possible this evening across
eastern Arkansas, western Tennessee, northern Mississippi, and the
Missouri Bootheel. The risk for a few tornadoes is expected to
redevelop Friday afternoon into the evening across parts of the
Mid-South and Tennessee Valley regions.

SURF: Swells produced by Laura continue to affect the U.S. Gulf
coast from the Florida Panhandle to Texas. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.


NEXT ADVISORY
-------------
This is the last public advisory issued by the National Hurricane
Center on this system. Future information on this system can be
found in Public Advisories issued by the Weather Prediction Center
