Tropical Storm Lisa Discussion Number  11

400 AM CDT Wed Nov 02 2022

A few hours ago, an Air Force Reserve Hurricane Hunter aircraft
reported 850-mb flight-level winds of 67 kt in the northeastern
eyewall and estimated 55-60 kt surface winds from the Stepped
Frequency Microwave Radiometer.  The minimum central pressure was
near 992 mb.  Since then, satellite imagery and radar data from
Belize show little change in organization, and based on these
observations the initial intensity remains 60 kt.

Lisa has 12-18 h before it makes landfall in Belize, and the
cyclone is expected to become a hurricane during that time.  The
forecast peak intensity of 75 kt is on the upper edge of the
intensity guidance.  After landfall, the cyclone should weaken as
it crosses Belize and northern Guatemala into southeastern
Mexico.  The center should emerge over the Bay of Campeche before
the 60 h point. However, strong upper-level winds should cause
enough shear to keep the cyclone from re-intensifying, and Lisa is
still forecast to weaken to a remnant low pressure area by 120 h.

The initial motion remains 280/13 kt. A ridge to the north will
continue to steer Lisa westward at a slightly reduced forward speed
through landfall.  The storm is the expected to follow the flow
around a low- to mid-level ridge into the Bay of Campeche in 48-60
h.  After that time, the increasingly shallow cyclone should turn
southward in the low-level flow.  The new forecast track is similar
to, but a little faster than the previous track as the guidance is
in good agreement on a faster motion through 72 h.


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 this
afternoon.

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

3. Tropical storm conditions are expected along portions of the
north coast of Honduras and Guatemala in the next several hours,
and over the eastern Yucatan Peninsula in the Tropical Storm
Warning areas beginning this 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.
