Tropical Storm Lisa Discussion Number  10
NWS National Hurricane Center Miami FL       AL152022
1100 PM EDT Tue Nov 01 2022

Air Force Reserve and NOAA Hurricane Hunters have found that Lisa is 
strengthening this evening.  Lisa is a small storm, with 
tropical-storm-force winds only extending out to 60 n mi from the 
center.  The minimum central pressure continues to fall, and the 
latest estimate from the dropsonde observations is 993 mb.  Data 
from the SFMR and Tail Doppler Radar show that surface or 
near-surface winds range between 55 to 60 kt, and the initial 
intensity is increased to 60 kt.

Lisa is on a strengthening trend.  Models suggest atmospheric and 
oceanic conditions should be conducive for additional 
intensification until the storm makes landfall in Belize within 24 
hours.  Therefore, steady to rapid intensification is still 
possible.  The official forecast shows a peak of 75 kt in 12 hours, 
however the true peak intensity will likely occur between 12 and 24 
hours and could be higher. Rapid weakening is expected after the 
storm moves inland, and Lisa is forecast to be a tropical depression 
in the Bay of Campeche in 72 to 96 hours and weaken to a remnant low 
by the end of the forecast period.

The storm is moving just north of west at 280/13 kt.  The track 
reasoning is unchanged.  A ridge to the north will continue to steer 
Lisa westward at a slightly reduced forward speed through landfall 
on Wednesday evening.  The storm is expected to follow the flow 
around the low-to-mid level ridge into the Bay of Campeche in 3 days 
or so.  The cyclone is then expected to turn southward in the 
low-level flow.  The NHC track forecast is shifted slightly 
northward from the previous advisory in the short term, and the 
Hurricane and Tropical Storm Warnings have been adjusted northward 
to account for this shift.


Key Messages:

1. There is potential for a life-threatening storm surge near where
the center of Lisa crosses the coast of Belize and extreme 
southeastern portions of the Yucatan Peninsula starting 
Wednesday afternoon.

2. Hurricane conditions are expected in the Bay Islands of Honduras
early Wednesday and along the coast of Belize and southeastern 
Yucatan by Wednesday afternoon.

3. Tropical storm conditions are expected along portions of the
north coast of Honduras and Guatemala beginning early 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, the southeastern 
portion of the Mexican state of Chiapas, and the Mexican state of 
Tabasco.
