Hurricane Hunter Flight Says Isaac Has Weakened Further

Hurricane Hunter Flight Says Isaac Has Weakened Further

Jeff Byard, associate administrator for response and recovery at the Federal Emergency Management Agency (FEMA), had hours earlier warned that "24 to 36 hours remain for significant threats" from heavy rain, storm surge and flooding. Gradual weakening is forecast during the next few days.

The tropical storm remnants are passing south of the island and moving west across the Caribbean region.

Wind speeds are expected to hit 55-65mph, with maximums of 70-80mph.

Since then, Isaac has meandered in the Caribbean Sea and, as a depression, lashed the Lesser Antilles Friday morning with rain squalls and 35 miles per hour winds.

Tropical Storm Joyce has weakened as it turns east-northeastward about 890 miles west-southwest of the Azores with winds at 50 mph and traveling east at 8 mph. Helene will end up dying out over the open Atlantic, with no chance to push towards the U.S. Little change in strength is forecast during the next 12 hours as Helene remains over warm sea surface temperatures.


The tropical storm is battling strong winds in the upper atmosphere and it is possible Isaac could degenerate into a tropical wave as it moves through the Lesser Antilles. This rainfall may cause unsafe flash flooding, N.H.C. said.

The storm is expected to produce 2 to 4 inches of rain, with near 6 inches possible in isolated areas, forecasters said.

Tropical Storm Isaac made its closest approach to St. Croix Thursday night, passing nearly 200 miles to the south and having no apparent impact on the territory as it made its leisurely way across the Caribbean.

It is predicted the Carolinas could begin feeling tropical storm force winds late Wednesday or early Thursday. The meteorological service of Antigua and Barbuda has issued a Tropical Storm Watch for Antigua and Montserrat.

States of emergency were declared in the Carolinas; Virginia; Washington, DC; and Maryland, where some coastal areas are still recovering from summer storms. Rip Currents: High risk for rip currents at all beaches today and likely into this weekend.
