Hurricane Helene tracking directly towards Ireland, forecaster warns

The NHC expects Isaac to move near or over the central Lesser Antilles on Thursday, move into the Eastern Caribbean Sea Thursday night, and move into the central Caribbean Sea by the weekend. "Gradual weakening is forecast over the next couple of days, and Helene is expected to become a tropical storm on Thursday". We have several storms to track in the Atlantic and another one in the Pacific heading towards Hawaii.

Rainfall totals of 2 to 3 inches with isolated maximum amounts of 4 inches are possible across the south-central portion of the Dominican Republic, southwest Haiti and Jamaica.

Isaac was moving west Wednesday afternoon at a speed of nearly 17 miles per hour. Behind Isaac, Hurricane Helene is picking up strength, with twist paces of more than 105 miles per hour as of Monday afternoon.

Meanwhile, what could be the world's most unsafe storm at the moment is Super Typhoon Mangkhut, which now has winds of 165 miles per hour (with 200 miles per hour gusts) and is taking aim on the Philippines, according to the Joint Typhoon Warning Center. "Heavy and long-lasting rainfall could lead to catastrophic flooding in inland parts of North Carolina, South Carolina and Virginia".

The Met Office issued two "yellow" alerts on Friday as the storm began creeping towards south-western corners of the United Kingdom and the tip of Ireland.

The center is slowing down and is expected to stall and perhaps wander around just off shore on Thursday, Friday and Saturday. National Hurricane Center (NHC) said on Wednesday, but a life-threatening storm surge and heavy rainfall were still expected.

Given its expected slow speed once it rolls ashore, they warned the heavy rain and storm could spread across a wide area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area.

While a tropical storm watch is in effect for St. Kitts and Nevis, at Pond Hill, Nevis, forecaster Harry W. Hallstrom said, "Isaac is getting ripped apart with wind shear".

Overnight, Isaac began to fall apart as it encountered increasing atmospheric winds that help shred storms and neared dry air. Forecasters also were tracking two other disturbances.

"Florence is forecast to be an extremely risky major hurricane as it approaches the USA coast", the NHC said.
