2002-09-14 · Upper Plaquemines, Louisiana

Wider weather episode

Hanna developed out of a broad area of disturbed weather and low pressure in the Gulf of Mexico. A tropical depression formed from the disturbance late on September 11th in the central Gulf of Mexico and meandered slowly across the central Gulf before becoming a tropical storm on the 13th about 255 miles south southwest of Pensacola, Florida. Tropical Storm Hanna moved northwest and then north and passed over extreme southeast Louisiana near the mouth of the Mississippi River early on the 14th and made landfall near the Mississippi and Alabama border midday on the 14th with 50 mph winds.Tropical Storm Hanna was an asymmetrical storm with the strongest winds confined to the east of the center. As a result, no tropical storm force winds were observed at any land locations. Rainfall amounts were less than 1 inch and no significant flooding occurred from high tides.
