CURRENT TROPICAL CYCLONES:

Tropical Cyclone 04L (Debby)…is located about 90 miles west-northwest of Raleigh, North Carolina…according to the NHC Advisory number 27

Tropical Cyclone 04L (Debby)

MAJOR FLOOD THREAT CONTINUES FOR PORTIONS OF WESTERN VIRGINIA

The depression is moving toward the north-northeast near 26 mph (43 km/h) and this motion is expected to slowly increase and shift to the northeast over the next day.

Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Little change in strength is forecast during the next 48 hours.

HAZARDS AFFECTING LAND

RAINFALL: Debby is expected to produce an additional 3 to 6 inches of rainfall with locally higher amounts, across portions of southeastern North Carolina leading to maximum storm total amounts as high as 15 inches. Additional rainfall of 1 to 3 inches over portions of eastern South Carolina will bring maximum storm total amounts as high as 20 to 25 inches. Considerable flooding is expected across portions of eastern South Carolina and southeast North Carolina through Friday.

From central North Carolina northward across portions of Virginia, 3
to 7 inches with local amounts to 10 inches, are expected through Friday. This rainfall will likely result in areas of considerable to locally catastrophic flash and urban flooding, especially in the terrain of western Virginia, with river flooding also possible.

From portions of Maryland north through Upstate New York and Vermont, 2 to 4 inches, with local amounts to 6 inches, are expected through Friday night. This will likely result in areas of considerable flash and urban flooding as well as river flooding.

For the remainder of northern New England, 1 to 3 inches, with local amounts to 4 inches, are expected into Saturday. Scattered instances of flash flooding are possible.

TORNADOES: A few tornadoes may occur tonight from eastern North Carolina into Virginia and Maryland. The threat for tornadoes will shift northward into parts of New Jersey, eastern Pennsylvania and southeast New York on Friday.

SURF: Large swells will continue to affect the Southeast and the Mid Atlantic coast for another day or so. These conditions are likely to cause life-threatening surf and rip current conditions.

>>> Near the Lesser and Greater Antilles:

A tropical wave located over the tropical Atlantic several hundred
miles west-southwest of the Cabo Verde Islands is producing widespread disorganized showers and thunderstorms. Any development of the wave should be slow to occur during the next couple of days while it moves westward across the central tropical Atlantic. Afterwards, conditions are expected to become more conducive for development, and a tropical depression could form while it approaches the Lesser Antilles by early next week. The system is then forecast to move generally west-northwestward and could approach the Greater Antilles by the middle part of next week.
