The Miami-based National Hurricane Center has upgraded Hurricane Watches to Hurricane Warnings along portions of the Florida Coast. The Hurricane Watch that was up from the Volusia-Brevard County line to the Flagler/Volusia County Line is now a Hurricane Warning.
With the expanded Hurricane Warning area, the warning area now includes the coast from Boca Raton to the Volusia/Brevard County Line, the Northwestern Bahamas, and the Central Bahamas. A Hurricane Watch is in effect for Hallandale Beach to south of Boca Raton, Florida.
A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Meanwhile, a Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous.
A Storm Surge Watch is also in effect for Jupiter Inlet to Ponte Vedra Beach, Florida. A Storm Surge Watch means there is a possibility of life-threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours.
A Tropical Storm Warning is also in effect from north of Ocean Reef to south of Boca Raton, Florida, as well as for Lake Okeechobee. A Tropical Storm Watch is in effect for the Flagler/Volusia County Line to Ponte Vedra,Beach Florida. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.
Maximum sustained winds in the hurricane are near 80 mph with higher
gusts. According to the National Hurricane Center, additional strengthening is expected through early Saturday, and Isaias is forecast to remain a hurricane for the next couple of days. The minimum central pressure reported by an Air Force Hurricane Hunter aircraft is 987 mb or 29.15 inches.
