90% chance per NHC 2pm , now appears as if it will develop.  There is a lot of spread in the intensity guidance, as one would expect with a small storm.

 

  Currently disorganized with multiple centers, it will probably consolidate near the centroid some time tonight or tomorrow.

Potential Tropical Cyclone Fifteen Discussion Number   1
NWS National Hurricane Center Miami FL       AL152022
500 PM EDT Sun Oct 30 2022

This morning we were fortunate to have concurrent NOAA and Air Force 
Reserve Hurricane Hunter missions, which provided a wealth of 
flight-level, Tail Doppler Radar, and dropsonde data over the system 
in the central Caribbean Sea. The data indicated that a 
well-defined, while somewhat broad, circulation had formed with a 
minimum pressure of 1005 mb. A combination of SFMR winds and surface 
dropsonde data also suggested that the system had 35-kt winds in its 
northern semicircle. With that said, the satellite presentation of 
the system currently lacks sufficient convective organization to be 
considered a tropical cyclone. However, given the well-defined 
center and tropical-storm-force winds, there is significant risk for 
tropical storm conditions in the near future in portions of Jamaica 
and Grand Cayman Island. With the expectation that this system will 
likely become a tropical storm soon, advisories have been initiated 
on Potential Tropical Cyclone Fifteen. 

The estimated motion of the disturbance is off to the west-northwest 
at 290/9 kt. This general motion is forecast to continue for the 
next day or so, as an expansive mid-level ridge is currently 
centered north of the system and expected to move westward with 
the cyclone. Toward the end of the forecast period, the ridge may 
nose further westward as a deep-layer trough becomes established 
well to the the northeast, which could result in a south of due 
west motion when the system approaches the coast of 
Belize.  Landfall is expected between the 72- and 96-hour forecast 
points. The initial NHC track forecast is roughly a blend of the 
latest GFS and ECMWF guidance, which is also quite close to  
the HCCA and TCVA consensus aids. 

Based on the current structure, it may take a bit longer for the 
convection to become sufficently organized to allow the formation of 
a tropical cyclone, but this is forecast to occur at some point 
tonight, likely during the typical diurnal maximum. After deep 
convection become better established, environmental conditions 
appear to be conducive for further intensification, especially in 
the 24-48 hour period when the vertical wind shear is expected to be 
lowest (5-15 kt) as the system traverses 29-30 C sea-surface 
temperatures. Mid-level relative humidity is quite low (55-60 
percent), but given the relatively low shear, this may act to keep 
the system's structure small with a constricted radius of maximum 
winds. The initial intensity forecast after 24 hours closely follows 
the latest HCCA and ICON intensity guidance, making the system a 
Category 1 hurricane in 60-72 hours. The system should weaken 
quickly over land and is forecast to dissipate before day 5. 

Based on the latest forecast, the government of Jamaica has issued 
a Tropical Storm Watch for Jamaica, and the government in the 
Cayman Islands has issued a Tropical Storm Watch for Grand Cayman 
Island. 


Key Messages:

1. Tropical storm conditions are possible within the Tropical Storm 
Watch areas beginning Monday for Jamaica and on Tuesday for Grand 
Cayman Island. 

2. Interests along the coast of Central America, especially near 
Belize, should monitor the progress of this system. Additional 
watches and warnings will likely be required early this week.

Potential Tropical Cyclone Fifteen Discussion Number 2
NWS National Hurricane Center Miami FL AL152022
1100 PM EDT Sun Oct 30 2022

Satellite imagery and data from a NOAA Hurricane Hunter aircraft
indicate there has been little change in the structure of the
disturbance this evening. Satellite imagery shows that the
low-level center is apparent in satellite imagery between two areas
of disorganized convection to the northwest of a loosely-curved
convective band. The aircraft data shows that the circulation at
460 mb is located to the southeast of the surface center and is not
well defined at that level. Dropsondes to the northeast of the
center showed surface winds of 30 kt, and drops near the center
suggest the central pressure is near 1005 mb. Based on these data,
the initial intensity remains 35 kt.

The estimated initial motion is a little to the left of the
previous advisory, 280/10 kt. A general westward to
west-northwestward motion is expected during the next 48 h or so
due to the presence of a westward moving mid-level ridge north of
the center. After that time, the ridge should build a little
faster toward the west and southwest, resulting in a south of west
motion as the system approaches Belize or the Yucatan Peninsula of
Mexico just after 72 h. The forecast guidance has shifted
southward through 60 h, and the new forecast track is nudged in
that direction. However, the new track lies to the north of the
various consensus models. It should be noted that the the forecast
track could undergo some additional adjustments until the
circulation center becomes better defined.

A combination of the current disorganized structure, moderate
west-northwesterly shear, and weakly convergent upper-level flow
should limit intensification for the next 12-24 h. However, the
system is still expected to become a tropical storm in about 12 h
when the convection increases during the diurnal maximum. After 24
h, increased upper-level divergence, decreased shear, and better
organization should allow a faster development rate, and the system
is expected to steadily strengthen. The new intensity forecast
follows the previous forecast in calling for the system to become a
hurricane before landfall in Belize or the Yucatan Peninsula, with a
forecast peak intensity of 70 kt being near the upper edge of the
intensity guidance.

No changes to the current watches are required at this time. A
Tropical Storm Warning may be necessary for Jamaica Monday morning
depending on the evolution of the track and the 34-kt wind radii.


Key Messages:

1. Tropical storm conditions are possible within the Tropical Storm
Watch areas beginning Monday for Jamaica and on Tuesday for Grand
Cayman Island.

2. Interests along the coast of Central America, especially near
Belize and the Yucatan Peninsula of Mexico, should monitor the
progress of this system. Additional watches and warnings will
likely be required early this week.

Tropical Storm Lisa Discussion Number   4
NWS National Hurricane Center Miami FL       AL152022
1100 AM EDT Mon Oct 31 2022

GOES-16 1-minute visible imagery indicates that the low-level 
circulation of the system has closed off again, although the system 
is still a bit elongated north-to-south.  Westerly shear has caused 
the center to be exposed to the west and north of the primary 
convective banding features.  NOAA Hurricane Hunter tail Doppler 
radar data also show that the low is tilted southeastward with 
height, a reflection of the current shear.  Still, the plane had 
numerous SFMR values of around 35 kt, and dropsonde data showed the 
pressure has dropped to 1003 mb.  These values are sufficient to 
call the system a tropical storm with an initial wind speed of 35 
kt.

After a dip southward overnight, Lisa is moving westward again at
about 12 kt.  The storm should move westward to west-northwestward
for the next day or two under a mid-level ridge to the north.  As
the ridge intensifies in a few days, Lisa is likely to move
westward, or possibly a little south-of-west, while it approaches
Belize.  Model guidance remains in very good agreement, and 
only a small southward adjustment was made to the previous forecast.

Lisa should encounter more conducive atmospheric and oceanic 
conditions for the next few days, with increasing mid-level 
humidities and generally lower shear.  The storm will likely still 
have some bouts with drier air infiltrating in the northwestern 
quadrant of the circulation, but the diminishing shear should lessen 
the impact of this factor.  Thus slow intensification is shown for 
the next few days, consistent with the interpolated previous 
forecast.  It should be noted that the new NHC forecast is on the 
high side of the guidance for this cycle, with a notable decrease of 
the forecast intensity in many of the models.  The official 
forecast is lower than the previous one, owing to the model trend, 
but it is preferable to wait another cycle to make any larger 
changes after the model suite ingests the plentiful aircraft data 
for the 12 UTC suite.


Key Messages:

1. Tropical storm conditions are possible on Jamaica today.

2. Interests along the coast of Central America, especially near
Belize and the Yucatan Peninsula of Mexico, should monitor the
progress of this system. Additional watches and warnings will
likely be required by late today.

Tropical Storm Lisa Discussion Number 6
NWS National Hurricane Center Miami FL AL152022
1100 PM EDT Mon Oct 31 2022

Lisa is gradually becoming better organized with the associated
convection deepening and expanding around the center. However, the
system still lacks banding features. The Air Force Hurricane
Hunters are currently investigating Lisa and so far have found
flight-level winds as high as 46 kt and peak SFMR winds of about 35
kt. This data supports maintaining the initial intensity of 40 kt.

The tropical storm is moving westward at about 10 kt. The track
forecast reasoning seems fairly straightforward. A low- to
mid-level ridge situated to the north of Lisa is expected to build
westward. This pattern should keep the storm on a steady westward
path, bringing the core of the cyclone near or just north of the Bay
Islands of Honduras late Tuesday night/early Wednesday and across
Belize by late Wednesday. The models are in fairly good agreement
through landfall, and the NHC track forecast is very similar to the
previous one during the next couple of days. After landfall, the
models diverge with some solutions showing a northwest track and
others a southwest motion. The NHC track forecast continues to split
the difference, and it is a touch south of the previous one to be a
little closer to the various consensus models.

The environmental conditions appear relatively favorable for Lisa
to strengthen during the next 36 to 48 hours. SSTs are quite warm
beneath the cyclone and the vertical wind shear is expected to be
low to moderate. There is some dry air near the system, however,
which might slow the rate of intensification. The NHC intensity
forecast follows the trend of the consensus models and continues to
show Lisa becoming a hurricane when it is over the Gulf of Honduras
early Wednesday, and it is expected to maintain that intensity when
it makes landfall. Rapid weakening is expected after the system
moves inland, and even though the forecast shows a 96-h point, it
is certainty possible that Lisa could have dissipated by then.

Key Messages:

1. Hurricane conditions are possible in the Bay Islands of Honduras
early Wednesday and along the coast of Belize by Wednesday
afternoon, where a Hurricane Watch is in effect.

2. Tropical storm conditions are expected along portions of the
north coast of Honduras, where a Tropical Storm Warning has been
issued. A Tropical Storm Watch is in effect for the
remainder of the coast of Honduras, the Caribbean coast of
Guatemala, and the southeastern Yucatan Peninsula of Mexico, where
tropical storm conditions are possible.

3. Localized flash flooding is expected across portions of the
eastern Yucatan Peninsula, Belize, and northern Honduras, including
the Bay Islands, starting late Tuesday continuing through Thursday.

4. There is potential for a dangerous storm surge near where the
core of Lisa crosses the coast of Belize.

Tropical Storm Lisa Discussion Number   8
NWS National Hurricane Center Miami FL       AL152022
1100 AM EDT Tue Nov 01 2022

An Air Force Reserve Hurricane Hunter aircraft has provided
critical data with Lisa this morning, showing that the storm has
started to intensify.  Flight-level winds have increased to
55 kt, with SFMR winds of 50-55 kt, and surface-reduced dropsonde 
data of about 50 kt.  Thus, the initial wind speed is set to 50 kt 
as a blend of these data, above the latest satellite 
classifications. 

Further intensification is likely with Lisa now having a small 
radius-of-maximum winds in light vertical wind shear, along with 
the deep warm waters of the northwestern Caribbean providing ample 
fuel.  The NHC intensity forecast calls for steady strengthening 
and shows Lisa becoming a hurricane in less than a day when it is 
near the Bay Islands of Honduras, and Lisa should intensify as it 
approaches Belize.  For now, rapid intensification is not forecast, 
but since the percentage chances of this occurrence from SHIPS are 
increasing, this possibility must be mentioned and the new forecast 
is higher than the bulk of the guidance.  After landfall, rapid 
weakening is expected and Lisa is forecast to degenerate to a 
post-tropical remnant low by 72 hours and dissipate shortly 
thereafter.

Lisa continues moving just north of due west or 280/12 kt.  No 
significant changes were made to the track forecast.  A strong low- 
to mid-level ridge located to the north of Lisa should keep the 
tropical cyclone on a generally westward track during the next 
couple of days.  This motion is expected to bring the core of the 
cyclone near the Bay Islands of Honduras by early Wednesday, and 
across the coast of Belize by late Wednesday.  The dynamical models 
remain in relatively good agreement, and the NHC track is near the 
middle of the guidance envelope.  


Key Messages:

1. Hurricane conditions are expected in the Bay Islands of Honduras
early Wednesday and possible along the coast of Belize by
Wednesday afternoon.  Hurricane conditions are possible in eastern 
Yucatan in the Hurricane Watch area Wednesday afternoon.

2.  There is potential for a life-threatening storm surge near where 
the center of Lisa crosses the coast of Belize and for the southern 
portions of the Yucatan Peninsula.

3. Tropical storm conditions are expected along portions of the
north coast of Honduras and Guatemala beginning tonight into 
Wednesday, and over the eastern Yucatan Peninsula in the Tropical 
Storm Warning areas beginning Wednesday afternoon.

4. Localized flash flooding is expected across portions of Belize, 
the Bay Islands of Honduras, northern Guatemala and the southeast  
portion of the Mexican state of Chiapas starting tonight through 
Thursday.
