Hurricane Helene has Britain in its sights

Hurricane Helene has Britain in its sights”

Hurricane Florence weakened to Category 2 storm overnight, but with sustained winds of 110 miles per hour, it was within 1 miles per hour of Category 3 and the wind field is expanding.

Emma Smith of the Met Office added: "Helene is moving up from the Atlantic towards us". No coastal watches or warnings are in effect, and the NHC forecast track shows the storm heading west towards Central America.

Although Florence was downgraded from Category 4 status, it is still considered an extremely unsafe storm with maximum sustained winds near 125 miles per hour.

Isaac is forecast to gradually weaken over the next few days, and could degenerate into a tropical wave at any time.

Tropical Storm Isaac is moving west in the Caribbean and will regain enough strength to become a hurricane again, forecasters said Tuesday.

Helene, which has been downgraded from a hurricane, is among a glut of tropical storms brewing in the region, with mass evacuations under way in southern USA states as Hurricane Florence barrels across Virginia and the Carolinas.

However, it is not expected to bring the severe weather seen during Storm Ophelia last October, which caused widespread damage and left three people dead.

That's almost double the wave heights documented on Tuesday, when the NHC said satellites had observed "an expansive area of wave heights 12 feet or greater" circulating around Hurricane Florence and peak waves of 45 feet near its center.

The U.S. National Hurricane Center (NHC) said Helene has 90 miles per hour winds, meaning it is a Category 1 storm.

Florence is now 485 miles from Wilmington, North Carolina. He added: "There's a lot of uncertainty around the developments of that low pressure system". Regardless of whether a system forms, they say heavy rain and gusty winds are likely along the Texas and Louisiana coast later this week.
