TROPICAL STORM ISAIAS
2:00 PM Advisory August 3, 2020
Tropical Storm Isaias is still expected to make landfall tonight as a Hurricane. At 2:00 PM, the center of Tropical Storm Isaias was located near latitude 31.2 North, Longitude 80.0 West. Isaias is moving toward the north near 13 mph and this general motion is expected to continue this afternoon. A turn toward the north-northeast along with a slight increase in forward speed is expected by early this evening, followed by a faster motion tonight and Tuesday. On the forecast track, the center of Isaias will pass well east of the Georgia coast through the afternoon and approach the coast of southern North Carolina within the hurricane warning area this evening.
The maximum sustained winds remain near 70 mph with higher gusts. Some strengthening is forecast this afternoon and early evening, and Isaias is expected to regain to hurricane strength just before the cyclone reaches the coast of southern NC tonight. Tropical storm force winds extend outward up to 125 miles from the center. The estimate minimum central pressure is 993 mb (29.32 inches).
The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach 3-5 feet above ground if the peak surge occurs at the time of high tide. The deepest waters will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large waves.
Hurricane conditions are expected within the hurricane warning area in North Carolina this evening through tonight, with tropical storm conditions beginning later today. Widespread tropical storm conditions are expected in the warning area with wind gusts to hurricane force possible. These winds could cause tree damage and power outages.
The Carolinas should expect 3-6 inches of rain with an isolated maximum totals of 8 inches. Heavy rainfall from Isaias will result in flash flooding some of which may be significant in eastern Carolina. A few tornadoes will be possible over North Carolina tonight into Tuesday morning.
Please be prepared for this storm and watch for future updates.
