Hazardous Coastal Conditions for the Mid-Atlantic; Storm System Approaching Southern Alaska

A Nor'easter will create hazardous marine and coastal conditions along the Mid-Atlantic coast through mid-week, with significant coastal flooding and beach erosion possible. Meanwhile, another strong storm system is forecast to bring high winds and heavy precipitation to portions of southern Alaska. Elsewhere, relatively benign weather is expected through the first half of the work week. Read More >

Tropical Storm Debra

August 26-29, 1978

Tropical Storm Debra originated from the interaction of a mid to upper level low that formed over Southern Florida late on August 24^th and a tropical wave from the Caribbean Sea. The mid to upper low drifted southwestward across the Yucatán Peninsula as the tropical wave was entering the Gulf on August 25^th. Increased showers and thunderstorms occurred near the disturbance, with Tropical Depression #5 forming by daybreak on August 26^th. The depression moved westward being steered by and mid to upper level ridge of high pressure over the Southern United States.

By August 27^th, the mid to upper level ridge shifted eastward as an upper level trough moved eastward over the Central United States. This allowed the depression to move northwest and eventually northward towards the Northwest Gulf Coast through August 28^th. The depression intensified and was named Tropical Storm Debra by early afternoon. Now heading in a north-northeast direction, Tropical Storm Debra made landfall shortly after 7 PM CDT August 28^th near Constance Beach, Louisiana with maximum sustained winds of 60 mph (50 knots) and a minimum central pressure of 1000 millibars (29.53 inches).

Debra weakened to a depression shortly after midnight on August 29th over Western Louisiana and merged with a frontal trough across Central Arkansas by the afternoon.
