Tropical Storm Isaac continues to weaken as it approaches the Caribbean

Tropical Storm Isaac continues to weaken as it approaches the Caribbean

Hurricane Florence is now generating waves up to 83 feet, almost double the height measured on Tuesday.

The NHC said Helene could bring 2 inches to 4 inches of rain to the Azores with isolated amounts up to 8 inches and life-threatening flash flooding.

Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center.

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A small-craft warning and a high-surf advisory will be in effect from 6 p.m., today until 6 a.m. Friday, September 14.

On Friday morning, the Met Office issued a yellow weather warning for western parts of the United Kingdom from 18.00 on Monday 17 September until midday on Tuesday, but the warning could be upgraded to red over the weekend.

Florence peaked at a terrifying Category 4 with top winds of 140 mph (225 kph) over warm ocean water before making landfall as a Category 1 hurricane at 7:15 a.m.at Wrightsville Beach, a few miles (kilometres) east of Wilmington and not far from the SC line.


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

National Hurricane Center Director Ken Graham said radar and rain gauges indicated some areas got as much as 2 1/2 feet of rain, which he called "absolutely staggering".

Gradual weakening is forecast during the next 48 hours, but Olivia is expected to remain a tropical storm as it moves over the main Hawaiian Islands. The upper level winds are light, meaning the storm is likely to maintain intensity, or even strengthen a bit before making landfall. Tropical storm conditions are possible within the tropical storm watch area on Thursday.

According to the National Hurricane Center, a burst of deep convection developed Thursday and covered the previously exposed center of Isaac Thursday evening, but there was evidence of northwesterly shear over the cyclone, causing some of the cloud cover to quickly blow off toward the southeast. According to the National Weather Service, the waves are produced by being trapped along with very strong winds moving in the same direction as the storm's motion.

"Interests elsewhere in the southeastern and mid-Atlantic states should monitor the progress of Florence", said the NHC.
