Broad Low Pressure Setting Up East Of Florida This Weekend; Weak Tropical Development Possible Next Week

We had a flurry of late-season tropical activity this week, including two simultaneous hurricanes in the Atlantic – Lisa and Martin – for only the 3rd time on record! Things are a bit quieter heading into the weekend, and the main story heading into next week will be the potential for some weak development east of Florida.

A broad area of low pressure is likely to form across the northeastern Caribbean Sea and southwestern Atlantic over the next coupe of days. It’s possible that this begins to take on some tropical characteristics next week, but any development should stay weak. As this moves in a general westward direction next week, it will lead to a string of days with some gusty winds and fast moving downpours for parts of the Southeastern U.S. Atlantic coast and Florida. In addition, some minor coastal flooding will be possible on Florida’s east coast due to the combination of strong onshore flow and predicted king tides.

Two Simultaneous November Hurricanes In The Atlantic For Only The Third Time On Record

1932, 2001, and now 2022 – the only years on record that we’ve had two November hurricanes in the Atlantic simultaneously. This time around it is Hurricane Lisa and Hurricane Martin.

Martin will continue to trek in a general northeastward direction through the North Atlantic over the next few days, ending up in the vicinity of Iceland by early next week.

Lisa, on the other hand, is headed for a landfall in Belize by Wednesday evening. This is a compact storm, so it’s more susceptible to quick changes in intensity. Max sustained winds were at 80 mph as of the 10AM CDT advisory, but there is a window for some additional strengthening right up until landfall. A storm surge of 4-7 feet is likely near and just to the north of where the storm makes landfall along the coast of Belize. Isolated rainfall totals up to 10″ are possible across Belize, northern Guatemala, and parts of southern Mexico.

What is left of the system should emerge over the Bay of Campeche in the far southwestern Gulf of Mexico by late Thursday or early Friday. At that point, strong southwesterly shear should cause it to weaken into a remnant area of low pressure.

Elsewhere, we’ll be keeping an eye on a broad area of low pressure moving north across Puerto Rico and the Dominican Republic this weekend. The odds of anything consequential developing are low, but the likelihood of this bringing higher rain chances next week to parts of Florida and Southeastern U.S. Atlantic coast are increasing.
