*Tropical Storm Elena*
August 29-September 2, 1979
Above: SMS-2 visible satellite image of Tropical Storm Elena at 9:00 AM CDT September 1, 1979, at landfall near Matagorda, TX. Tropical Storm Elena originated from a tropical wave that emerged from the African coast August 17th. The wave moved across the tropical Atlantic and Caribbean Islands the next several days with little additional organization, crossing Florida on August 27^th. The wave moved westward into the Gulf on August 28^th, gradually gaining organization. Late in the afternoon on August 29th, an Air Force reconnaissance flight confirmed that Tropical Depression #10 formed about 200 miles south of the mouth of the Mississippi River. A mid to upper level ridge over the Southern United States and Northern Gulf steered the depression on a general west-northwest path south of the Louisiana coast. The depression strengthened to Tropical Storm Elena by the afternoon of August 30^th. Tropical Storm Elena began to move northwest and eventually northward towards the Texas coast on August 31^st through September 1^st as the mid to upper level trough over the Central United States weakened the ridge over the Northern Gulf. Weak northerly sheer noted in animated satellite imagery likely inhibited development, with Tropical Storm Elena remaining a weak tropical storm. The highest sustained winds of 40 mph (35 knots) continued through landfall at Matagorda, Texas around 9 AM CDT September 1^st. Elena weakened back to a depression immediately after landfall, and dissipated later that evening. Click here for an interactive track of Tropical Storm Elena.
