Latest Update on Hurricane Helene, Tropical Storm Isaac, Gulf Depression

Overnight, Isaac began to fall apart as it encountered increasing atmospheric winds that help shred storms and neared dry air. It was located 85 miles from Wilmington at 8 p.m. Thursday and its eye was expected to make landfall Friday, the advisory said.

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

"Overcast with moderate to heavy rain for south-west England, Wales, Ireland, north-west England and Scotland with fresh to strong and gusty southerly winds through the afternoon and evening".

"It's not a zero event".

The storm is likely to die out by Wednesday, the forecaster said.

Helene is one of three major storms now swirling in the Atlantic.

"We do not anticipate experiencing any tropical storm or hurricane force winds, but we could experience rain and will be placed under a flash flood watch", said Governor Kenneth Mapp in a release issued late Thursday. "It's a nasty interplay that makes it very hard".

The hurricane center said Isaac is expected to weaken in the coming few days. The forecast was complicated because the storm was still small, allowing it to quickly change. The winds of Isaac are not expected to affect the Virgin Islands.

Florence, however, continues to threaten the east coast as a fierce storm that could trigger flooding as far south as Georgia. Sustained winds slowed slightly to 125 miles per hour Tuesday afternoon, making it a Cat 3 storm. It's expected be south of Jamaica by Sunday morning. Earlier forecasts showed that the storm was slated to directly hit around North and SC.

There is the potential for damaging winds with gusts up to 70mph possible, with sustained winds of 30 to 40mph.

The NHC is estimating that as many as 20 inches of rain could fall in some places along the southern North Carolina coast while bringing in excess of 10 inches of rain in parts of SC.

The National Hurricane Center downgraded Isaac to a tropical storm overnight but said Tuesday that it could be "at or near hurricane levels" on Thursday, when it approaches the Lesser Antilles Islands. Storm winds could intensify through the day and tonight, but weaken slightly Thursday as it nears the coast.

"The rain's going to be around for a long time", he said.

Behind Isaac, Hurricane Helene also continued to deliver good news.

As of Thursday morning, forecast models showed the storm bringing more rain than originally thought - officials now predict 35 inches of rain will fall in a two-day period as Florence, now a Category 2 storm with 110 miles per hour sustained winds, will stall over Wilmington after making landfall early Friday morning.

A system in the central Gulf of Mexico was a little less certain.

Tropical Storm Watches were also discontinued for St. Maarten, St. Martin, Saba and Eustatius.
