Tropical Storm Isaac reforms, remains unpredictable

Tropical Storm Isaac reforms, remains unpredictable

As three powerful storms march one by one across the Atlantic Ocean toward the U.S. East Coast and the Caribbean, a fourth is getting ready to roll over the Hawaiian Islands.

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.

More than 2 feet of rain already had fallen in places, and the drenching went on and on as Florence, a hurricane-turned-tropical storm, practically parked itself over the two states. A Tropical Storm Watch is in effect for Antigua and Barbuda, Montserrat, and St. Kitts and Nevis. In addition to wind impacts, there's going to be a unsafe storm surge ("wall of water" that arrives) and then persistent rainfall. Tropical storms generate winds between 39 and 73 miles per hour, just below hurricane force. Satellite images show very little left as a recognizable tropical storm.

Given the lack of deep convection to sustain the cyclone, continual gradual weakening is expected.

A similar section of Wales and the Cornish peninsular are also expected to bear the brunt of any storm-like weather, although much of the rest of England could be noticeably windier by the time Helene hits land on Tuesday morning.

North Carolina Gov. Roy Cooper called Florence an "uninvited brute" that could wipe out entire communities as it grinds across the state.

Terrance O'Shaughnessy says radar, satellites and fighter jets are used to identify aircraft and determine appropriate responses. Tuesday's incident comes just a week after a similar interception of Russian bombers south of the Aleutian Islands.

Friday, then stall over the Wilmington region, dumping up to 35 inches of rain and prompting worry of "extreme" flash flooding. On Thursday morning, South 17th Street, usually teeming with commuter traffic by 6:30 a.m., was almost devoid of cars.

All of those variables were caused by continuing to be on the ropes and the constant pressure applied by Golovkin. The two fighters didn't engage in the traditional faceoff after Wednesday's press conference at the MGM Grand.

In North Carolina, a storm-surge pushed floodwater miles inland. Though there now are no coastal watches or warnings, over the next couple days the disturbance could produce gusty winds and rain storms for Hispaniola and Jamaica.

An update from the National Hurricane Centre (NHC) said today several inches of rain were expected in the Azores.

"Isaac continues to move westward at 17 miles per hour or 28 km/h The center of this system is now passing to the north of Barbados".

Forecasters were monitoring five tropical systems in the Atlantic Basin, with the strongest, Category 4 Hurricane Florence, threatening the Carolinas.

The agency is also monitoring a tropical disturbance that has a 60 percent chance of forming a tropical storm.

Met Office meteorologist Alan Deakin said: "Hurricane Helene may influence things in combination with an area of low pressure over the coming days".
