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.
