Florida - Wednesday September 27, 2023: The National Hurricane Center (NHC) is giving Invest-91, a disturbance in the central tropical Atlantic, a 90% chance of development with the next 48 hours. While Invest-91 will likely become a tropical depression, computer models predict it will turn northward later this week, like many of the storms that preceded it.
Elsewhere, Tropical Storm Phillipe remains active ahead of Invest Area-91, but it is forecast to peter-out within the next few days, reaching Puerto Rico possibly by Monday as a depression with winds of less than 39 mph.
Disturbance #1 - Central Tropical Atlantic - Invest 91
Showers and thunderstorms continue to show signs of organization in association with Invest-91, an area of low pressure located roughly halfway between the Cabo Verde Islands and the Lesser Antilles near 13 north latitude and 44.5 west longitude.
A large area of fresh to near-gale force east to southeast winds is present from 09 north to 20 north latitude, between 36 west and 45 west longitude. Seas have risen to between 8 and 11 feet. Gale force winds are expected to develop in this area by this evening and a Gale Warning has been issued.
Environmental conditions are forecast to be conducive for development, and a tropical depression or storm is expected to form in the next day or so while the system moves west-northwestward across the central tropical Atlantic.
The chance of development within the next 48 hours is high.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.
