Low Hits Florida, Ernesto and Florence Strengthen

JACKSONVILLE, Florida — At 2 a.m. on August 5, 2012 Eastern Daylight Time, NOAA’s National Hurricane Center in Miami, Florida, issued a tropical weather outlook due to the development of Tropical Storm Florence in the Atlantic Ocean as well as a low pressure system over Florida while Tropical Storm Ernesto still churns in the Caribbean.

UPDATE: Sahara Winds Weaken Florence, Ernesto To Hit Mexico

The system closest to Florida (marked as #1 on the above map), which made landfall near Cape Canaveral, Florida, is a trough of low pressure which continues to produce disorganized showers and thunderstorms extending from northeastern Florida eastward for a couple hundred miles. NOAA says that development of this system is not expected as it is anticipated to move farther inland across northern Florida over the next day or so. This system has a low chance (near 0%) of becoming a tropical cyclone during the next 48 hours. Locally heavy rain and gusty winds are possible across portions of the Florida Peninsula today.

Tropical Storm Ernesto is located 290 miles southeast of Kingston, Jamaica moving west at 22 miles per hour with maximum sustained winds of 60 miles per hour. NOAA says the center of Ernesto will move farther into the central Caribbean Sea towards the Yucatan Peninsula.

NOAA’s storm tracker forecasts that Tropical Storm Ernesto will continue on its west-northwestward track through Thursday. The storm is predicted to remain at tropical storm strength on Sunday before reaching just south of the island nation of Jamaica. The storm is expected to reach hurricane strength on Monday near Honduras.

Tropical Storm Florence is located over the eastern tropical Atlantic about 600 miles west of the Cape Verde Islands moving west-northwest at 16 miles per hour with maximum sustained winds of 60 miles per hour.

NOAA’s storm tracker forecasts that the Tropical Storm Florence will continue on its west-northwestward track through Thursday. The storm is predicted to weaken to tropical depression strength on Thursday before reaching just north of the island nation of Puerto Rico.
