BULLETIN
Post-Tropical Cyclone Jerry Advisory Number 33
NWS National Hurricane Center Miami FL AL102019
1100 AM AST Wed Sep 25 2019

...WEAKENING JERRY APPROACHING BERMUDA...


SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION
-----------------------------------------------
LOCATION...32.0N 66.8W
ABOUT 120 MI...190 KM W OF BERMUDA
MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H
PRESENT MOVEMENT...ENE OR 70 DEGREES AT 10 MPH...17 KM/H
MINIMUM CENTRAL PRESSURE...998 MB...29.47 INCHES


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

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Bermuda

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within the
next 12 to 24 hours.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone Jerry
was located near latitude 32.0 North, longitude 66.8 West. The
post-tropical cyclone is moving toward the east-northeast near 10
mph (17 km/h). A continued east-northeasterly motion is expected
for the next couple of days, followed by a turn toward the east on
Friday. On the forecast track, the center of Jerry is expected to
pass near or over Bermuda later today.

Maximum sustained winds have decreased to near 40 mph (65 km/h) with
higher gusts. Continued gradual weakening is expected during the
next few days.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.

The estimated minimum central pressure is 998 mb (29.47 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Jerry can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC
and on the web at www.hurricanes.gov/text/MIATCDAT5.shtml.

WIND: Tropical storm conditions are expected on Bermuda by this
afternoon and could continue through this evening.

RAINFALL: Jerry is expected to produce 1 inch or less of rainfall
across Bermuda through tonight.

SURF: Swells generated by Jerry will continue to affect Bermuda
during the next few days. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.


NEXT ADVISORY
-------------
Next intermediate advisory at 200 PM AST.
Next complete advisory at 500 PM AST.

Post-Tropical Cyclone Jerry Discussion Number 33
NWS National Hurricane Center Miami FL AL102019
1100 AM AST Wed Sep 25 2019

Jerry remains devoid of deep convection in an environment of dry
mid-level air and strong westerly shear. Data from a new
scatterometer pass indicate that the maximum winds are no more
than 35 kt, and even that value could be generous. The system
should remain in a hostile environment for the next few days, and
simulated satellite imagery from the global models suggest that no
significant deep convection will redevelop within it. Therefore
the official intensity forecast calls for the cyclone to gradually
spin down over the next 2-3 days. The NHC intensity forecast is
just slightly below the model consensus.

The cyclone has turned toward the east-northeast with some increase
in forward speed, and the initial motion estimate is 060/8 kt.
Jerry should continue to move east-northeastward, to the south of
the main belt of mid-latitude westerlies, for the next day or two.
Later in the forecast period, the weak cyclone is expected to turn
east-southeastward along the northeastern periphery of a subtropical
high pressure area, and dissipate. The official track forecast
continues to follow the NOAA corrected consensus guidance rather
closely.


Key Messages:

1. Tropical-storm-force winds are expected on Bermuda later today.
Large swells are also expected to affect the coast of Bermuda during
the next few days. These swells could cause life-threatening rip
currents. See products issued by the Bermuda Weather Service for
more information.

BULLETIN
Post-Tropical Cyclone Jerry Advisory Number 34
NWS National Hurricane Center Miami FL AL102019
500 PM AST Wed Sep 25 2019

...POST-TROPICAL CYCLONE JERRY NO LONGER HAS SUSTAINED TROPICAL
STORM FORCE WINDS...
...THIS IS THE LAST ADVISORY...


SUMMARY OF 500 PM AST...2100 UTC...INFORMATION
----------------------------------------------
LOCATION...32.2N 65.6W
ABOUT 45 MI...75 KM W OF BERMUDA
MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H
PRESENT MOVEMENT...ENE OR 70 DEGREES AT 12 MPH...19 KM/H

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

The Bermuda Weather Service has discontinued the Tropical Storm
Warning for Bermuda.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

There are no coastal watches or warnings in effect.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Jerry
was located near latitude 32.2 North, longitude 65.6 West. The
post-tropical cyclone is moving toward the east-northeast near 12
mph (19 km/h). A turn toward the east and east-southeast is
expected over the next couple of days. On the forecast track, the
center of Jerry is expected to pass near or over Bermuda in a few
hours.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Gradual weakening is expected during the next few days.

The estimated minimum central pressure is 999 mb (29.50 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical-storm-force wind gusts are possible over Bermuda
during the next several hours, especially at elevated sites.

RAINFALL: Jerry is expected to produce 1 inch or less of rainfall
across Bermuda through tonight.

SURF: Swells generated by Jerry will continue to affect Bermuda
during the next few days. 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. Additional information on this system can be
found in High Seas Forecasts issued by the National Weather Service,
under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at
ocean.weather.gov/shtml/NFDHSFAT1.php

Post-Tropical Cyclone Jerry Discussion Number 34
NWS National Hurricane Center Miami FL AL102019
500 PM AST Wed Sep 25 2019

Multiple scatterometer passes over Jerry indicate that the cyclone
no longer has sustained tropical-storm-force winds. Therefore
Jerry is now a remnant low, and the Bermuda Weather Service has
discontinued the Tropical Storm Warning for Bermuda. However, wind
gusts to tropical storm force are still possible on the island
during the next few hours, especially at elevated observing sites.
Based on the scatterometer data, the current intensity is estimated
to be 30 kt. The low-cloud swirl is becoming less well-defined, and
since the system will continue moving through a hostile environment
of strong shear and dry mid-level air, steady weakening is likely.
The cyclone should dissipate in 2-3 days. The NHC intensity
forecast is close to the latest intensity model consensus.

The system is moving east-northeastward at a slightly faster clip,
or 070/10 kt. A gradual turn to the east and east-southeast is
forecast as the cyclone moves along the southern edge of the band of
mid-latitude westerlies, and then turns to the right along the
northeastern periphery of a subtropical anticyclone before
dissipating.

This is the last advisory on Jerry.

FORECAST POSITIONS AND MAX WINDS

INIT 25/2100Z 32.2N 65.6W 30 KT 35 MPH...POST-TROP/REMNT LOW
12H 26/0600Z 32.8N 63.8W 30 KT 35 MPH...POST-TROP/REMNT LOW
24H 26/1800Z 33.7N 61.5W 25 KT 30 MPH...POST-TROP/REMNT LOW
