Met Office 'danger to life' warning as winds to hit Northern Ireland

Met Office 'danger to life' warning as winds to hit Northern Ireland

In a 2 p.m. advisory, forecasters said sustained winds remained at 60 miles per hour, down from 75 miles per hour Monday.

On the right side of this view is Helene, a Category 2 hurricane that will likely peter out in the Atlantic without making landfall, according to the latest update from the National Hurricane Center (NHC), a division of NOAA.

In contrast, no coastal watches or warnings were in effect for Helene, but residents of the Azores were encouraged to monitor the storm.

Isaac, with winds of 50 miles per hour, had weakened as it tracked westward toward the Caribbean, according to the National Hurricane Center, and may not survive beyond the next few days.

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 US National Hurricane Centre in its 8 a.m. tropical storm update reported Tropical Storm Isaac's centre was 25 miles east of Dominica and 80 miles southeast of Guadeloupe.

Far from this hurricane parade on the other side of the globe, Tropical Storm Olivia is flying solo east of Hawaii.

About halfway between Hurricane Florence and Hurricane Helene is the small but unsafe Tropical Storm Isaac, which was downgraded from hurricane status early this morning (Sept. 11).

Florence is now 485 miles from Wilmington, North Carolina. Storm winds could intensify through the day and tonight, but weaken slightly Thursday as it nears the coast.

Isaac is expected to be near hurricane strength when it moves through the Lesser Antilles, with some weakening forecast afterward on Friday and Saturday.

The storm is likely to die out by Wednesday, the forecaster said. Regardless of development, heavy rainfall and gusty winds are expected across portions of northeastern Mexico, Texas, and Louisiana late this week.
