Hurricane Helene to affect all Azores islands - IPMA
Sep 17 2018
In the Atlantic, while Joyce is far out to sea and poses no immediate threat to land, 70-mph Helene is forecast to roar near the Azores on Saturday and Sunday, the National Hurricane Center said. The storm has 45 miles per hour sustained winds with higher-speed gusts.
All watches and warnings that had been issued on neighboring islands were canceled Thursday.
NHC forecasters say that a slow southwestward motion is expected for the next couple of days.
The specialists refer to the probability that it will be reoriented towards the British Isles in an extratropical cyclone condition.
Tropical storm warnings were in effect for Martinique, Dominica and Guadeloupe, while watches were in effect for Montserrat, St. Kitts and Nevis, Antigua, and Saba and St. Eustatius.
"A life-threatening storm surge is highly likely along portions of the coastline of SC and North Carolina, and a Storm Surge Warning is in effect for a portion of this area", the National Hurricane Center said Wednesday.
At 500 PM EDT (2100 UTC), the center of Hurricane Florence was located near latitude 30.9 North, longitude 72.5 West. Florence is moving toward the northwest near 16 miles per hour (26 km/h), and this general motion, accompanied by a gradual decrease in forward speed, is expected to continue through Saturday.
The poorly organized, 45-mph storm is not expected to strengthen but should maintain its tropical storm strength for the next few days.
As of the 11:00 am Advisory, bands of rain from Isaac will continue to affect the Lesser Antilles. That would make five named storms traversing the Atlantic simultaneously, for the first time on record. The storm is expected to impact the windward and leeward islands on Thursday. Wind gusts in the area may be considerably higher.
All tropical lows are formed the same way, but once a hurricane crosses the International Date Line in the Pacific Ocean it becomes a Typhoon.
Rip currents will remain high and seas will continue to be close to 10 feet just off the coast.
