Excessive Rainfall Possible This Weekend; October Heat Wave in California

A slow moving front will be the focus area for heavy to excessive rainfall and a threat for flash/urban flooding across the northern Gulf Coast and Southeast U.S. through this weekend. Abnormally hot, potentially record-breaking, temperatures will impact southern California and stretch north toward the Bay Area and Central Valley into next week. Read More >

Hurricane Debra

July 22-27, 1959

An area of disturbed weather originating over the Bahamas moved across the Gulf July 20^th and 21^st. The disturbance gradually organized into a tropical depression late on July 22^nd about 150 miles south of the Louisiana coast. The depression moved slowly to the west being steered by a mid to upper level ridge to the north. The depression, slow to organized at first, became Tropical Storm Debra the afternoon of July 23^rd.

Tropical Storm Debra rapidly intensified overnight, and by daybreak on July 24^th, had attained hurricane strength. An early radar photo (owned by Dow Chemical Company in Freeport, Texas) at 7:33 AM CST July 24^th showed a well-defined eye and banding radar echoes associated with Hurricane Debra centered just off the upper Texas coast.

Weakening of the mid to upper level ridge allowed Hurricane Debra to move slowly northward, slowly intensifying for the remainder of the day. Hurricane Debra made landfall between Freeport and Galveston, Texas around 11 PM CST July 24^th with maximum sustained winds of 85 mph (75 knots) and a minimum central pressure of 980 millibars (28.94 inches). Debra was downgraded to a strong tropical storm by daybreak July 25^th as the center was passing over the Houston metropolitan area. Debra further weakened to a tropical depression early on July 25^th moving across the remainder of East Texas and Oklahoma before dissipating on July 27^th.
