Widespread tropical storm-conditions are expected around the region, most of Tuesday
PHILADELPHIA — Tropical Storm Isaias is getting better organized and expected to make landfall Monday night in the Carolinas as a hurricane with dangerous winds and storm surge.
The 5pm Monday forecast from the National Hurricane Center predicts strong winds and heavy rainfall will be likely from the eastern Carolinas to the Mid-Atlantic coast, Monday night and Tuesday.
Maximum sustained winds are at 70 mph and tropical storm-force winds extend up to 125 miles from the center.
A Tropical Storm Warning is in effect from North Carolina up to Maine, among other places. That includes our entire coastline and Delaware Bay. A Tropical Storm Warning means tropical storm conditions are expected somewhere within the warning area, generally within 36 hours.
At 5pm, Isaias was moving NNE at about 16 mph. That’s expected to continue along with getting faster, Monday night and again Tuesday.
The center of Isaias should make landfall around the South Carolina-North Carolina border, Monday evening. Then, Tuesday, the center will move inland across eastern North Carolina and along the coasts of the Mid-Atlantic states, before continuing across the northeast on Tuesday night.
Widespread tropical storm-conditions are expected around the Philadelphia region, from early Tuesday through the evening. The National Weather Service is forecasting winds of 40 to 50 mph, and gusts up to hurricane force (74 mph) possible.
The wind could cause significant damage to trees and cause power outages. There could also be damage to roofing and siding materials, along with porches, awnings, carports, and sheds. You’re urged to pick up unsecured lightweight objects that could become dangerous projectiles.
We could get 3 to 6 inches of rain, with isolated areas getting totals of 8 inches. The heavy rain is expected to cause flash and urban flooding, some of which may be significant.
Storm surge around the Delaware and New Jersey coasts could reach 1 to 3 feet above ground if the peak surge occurs during high tide.
Plus, a couple of tornadoes will be possible on Tuesday from eastern Virginia northeastward into southern New England.
