A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 36 hours in the indicated locations. Hopefully, Hurricane Florence will pass without causing much damage. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other risky conditions.
The local authorities declared the state of emergency across North Carolina, South Carolina, and Virginia due to the approaching of the Hurricane Florence, while millions of residents of the coastlines have been asked to leave their homes. A watch is typically issued 48 hours before tropical-storm-force winds are expected to arrive, which makes outside preparations hard or risky - and Tropical-storm-force winds are possible within the tropical storm watch area today.
"Outside the warning area, there will be blustery conditions with increasing amounts of cloud and rain".
Computer models are in general agreement that Subtropical Storm Joyce will move northeasterly across the Atlantic towards Europe.
First of all, a tropical cyclone is a large cluster of rain and wind, sometimes reaching wind speeds of over 160 miles per hour.
Elsewhere in the Atlantic, there are two areas being watched for potential tropical development.
Storm Surge Inundation: Up to 2 to 4 feet of inundation is possible in portions of the Storm Surge Watch area Friday into Saturday. Based on the latest advisory from the National Hurricane Center, the earliest reasonable arrival of tropical storm force winds in SC is Thursday afternoon.
Maximum sustained winds remain near 60 miles per hour (95 km/h) with higher gusts.
Hurricane Helene now has 85 miles per hour wind and is tracking north as a Cat 1 Hurricane.
Some slight strengthening is possible during the next couple of days.
Saint Lucia was spared the effects of heavy rainfall associated with Tropical Storm Isaac which was expected to produce 50 mm - 100 mm on the island from September 12 - 14, 2018.
The estimated minimum central pressure is 949 mb (28.03 inches). This rainfall may cause unsafe flash flooding.
