Re: EPAC: INVEST 97E
11 AM PDT TWO up to 70%-90%
Showers and thunderstorms have increased and become a little better
organized in association with a broad area of low pressure located
several hundred miles south of Manzanillo, Mexico. Environmental
conditions appear conducive for continued development of this
system, and a tropical depression is likely to form during the next
couple of days while the low moves west-northwestward to westward at
about 10 mph, away from the coast of Mexico.
* Formation chance through 48 hours...high...70 percent
* Formation chance through 5 days...high...90 percent

Re: EPAC: INVEST 97E
Shower and thunderstorm activity has increased in organization since
yesterday in association with a broad area of low pressure located
several hundred miles south of Manzanillo, Mexico. Environmental
conditions appear conducive for additional development and a
tropical depression is likely to form during the next couple of days
while the low moves westward to west-northwestward at about 10 mph,
away from the coast of Mexico.
* Formation chance through 48 hours...high...70 percent
* Formation chance through 5 days...high...90 percent

Re: EPAC: INVEST 97E
Satellite images indicate that the area of low pressure located
about 350 miles south-southwest of Manzanillo, Mexico, has become
better defined this morning. Associated shower and thunderstorm
activity is showing some signs of organization, and a tropical
depression is likely to form during the next day or two while the
low moves west-northwestward at about 10 mph, away from the coast
of Mexico.

Re: EPAC: INVEST 97E
Showers and thunderstorms have increased and become a little better
organized during the last several hours in association with a low
pressure system located about 300 miles south-southwest of
Manzanillo, Mexico. Continued development is expected, and a
tropical depression is likely to form later today or on
Tuesday while the low moves west-northwestward at about 10 mph, away
from the coast of Mexico.

Re: EPAC: FIVE-E - Tropical Depression
TROPICAL DEPRESSION FIVE-E DISCUSSION NUMBER 1
NWS NATIONAL HURRICANE CENTER MIAMI FL EP052016
300 PM MDT MON JUL 11 2016
Satellite data indicate that the area of low pressure located a few
hundred miles south-southwest of Manzanillo, Mexico, has developed
sufficiently organized deep convection and a well-defined center of
circulation. On this basis, the system is being declared a tropical
depression, the fourth one in the past 10 days in the eastern North
Pacific basin. The initial intensity of 30 kt is based on a pair of
ASCAT passes from a few hours ago that showed winds in the 25-30 kt
range.
The initial motion of the depression is uncertain since it is still
in its formative stage, but the best estimate using microwave fixes
is 315/8 kt. A turn to the west with a slight increase in forward
speed is expected to begin on Tuesday and persist through the
remainder of the period as mid-level ridging becomes better
established to the north of the cyclone. This track takes the
system away from the coast of Mexico. The models are in relatively
good agreement, and the NHC track forecast lies close to the
consensus aids.
Strengthening seems likely during the next 2 to 3 days while the
vertical shear is expected to be light to moderate, the atmosphere
relatively moist, and the waters beneath the cyclone sufficiently
warm. After that time, the cyclone is expected to move near the cold
water wake left behind from Blas and Celia and then ultimately cross
the 26 C isotherm in 4 to 5 days. As a result, the NHC intensity
forecast shows the strength of the system leveling off in the 3 to 5
day time frame. This prediction is a little above the intensity
model consensus.

Re: EPAC: FIVE-E - Tropical Depression
TROPICAL DEPRESSION FIVE-E DISCUSSION NUMBER 2
NWS NATIONAL HURRICANE CENTER MIAMI FL EP052016
900 PM MDT MON JUL 11 2016
Convective banding associated with Five-E has increased in
organization this evening. Accordingly, the SAB and TAFB Dvorak
current intensity numbers have increased to a 2.0 from both
agencies, corresponding to an intensity of 30 kt. Earlier
scatterometer data suggested higher winds than given by Dvorak
estimates, however, so the system may already be a tropical storm.
The environment in which Five-E is moving over and through - quite
warm SSTs, a very moist atmosphere, and moderate to low tropospheric
vertical shear - is likely to promote steady intensification during
the next three days. Around days 4 and 5, however, the cyclone
should be encountering the cool wake produced by Hurricanes Blas and
Celia. This sub-26 deg C water and more stable environment may
cause the system to gradually weaken at that time. The intensity
forecast is closest to an HWRF dynamical/SHIPS statistical model
blend through 72 h, and to SHIPS alone at days 4 and 5, and is very
similar to that from the previous advisory.
The tropical cyclone is moving at 320/8 kt, though the current
position and motion are somewhat uncertain because of the lack of
useful microwave imagery passes this evening. The system should
bend to a due west heading by tomorrow, as the deep-layer ridge to
its north builds in and strengthens. The model guidance is tightly
clustered through all five days and the NHC track prediction is
nearly the same as that from the previous advisory. The tropical
cyclone will remain out to sea with no threat to land for the next
several days.

Re: EPAC: FIVE-E - Tropical Depression
TROPICAL DEPRESSION FIVE-E DISCUSSION NUMBER 3
NWS NATIONAL HURRICANE CENTER MIAMI FL EP052016
300 AM MDT TUE JUL 12 2016
Satellite images indicate little overall change to the depression
during the past several hours. Convection has been flaring up and
down without any apparent increase in organization. A pair of
ASCAT passes showed maximum winds of 25 to 30 kt, so the initial
wind speed will stay 30 kt.
The initial motion has turned west-northwestward, and recently the
depression may even be moving due westward. A westward or west-
southwestward course is expected for the next 2-3 days due to a
building ridge over the eastern Pacific. Thereafter the system
should resume a track toward the west or west-northwest, with some
differences noted in the strength of the ridge at long range.
Overall, the model consensus has generally shifted southward by
about 30 n mi at most time intervals, and the official forecast will
follow that trend.
The intensity forecast is tricky since it is becoming more related
to the track forecast. While the overall environment looks conducive
for strengthening for a few days, the southward shift in the
cyclone's predicted path increases the chances that the system
encounters the cool wake of Blas and Celia. For now it is expected
to stay just to the north, so only a slight reduction is made to the
previous official forecast. The latest forecast is similar to the
intensity consensus for the first couple days, and remains above
that at longer range, mostly out of respect for a rather low-shear
environment forecast by the global models by late week. It is
worth noting, and probably should be no surprise, that the intensity
guidance has a rather wide range for this forecast, with the
GFS-based COAMPS-TC model showing no significant strengthening and
the HWRF model making the cyclone a hurricane in 36 hours.
