Texas
As the storm was approaching, the National Weather Service issued flash flood watches from Freeport to Sabine Pass, Texas.[9] Rainfall from the storm peaked at 18.29 inches (465 mm) in the town of Nederland.[10] A 24-hour precipitation record of 17.16 inches (436 mm) was reported at the Southeast Texas Regional Airport in Beaumont.[1] Due to heavy rainfall, an automobile accident in Beaumont resulted in one fatality.[1] A police officer in Beaumont noted that almost every street in the city was flooded.[11] The heavy rainfall resulted in considerable flash flooding in eastern Texas, causing residents to evacuate their homes. Flood waters also forced the shutdown of Interstate 10.[1] According to a police spokesman, at least 60% of streets in Port Arthur were inundated by water.[11] In Orange County, two people were injured in automobile accidents.[9] Along Highway 124, a bayou overflowed its bank.[12] Because there were numerous inundated streets, police barricaded roads in Beaumont, Bridge City, Orange, Vidor, and Port Arthur.[13] A sewer system in Roscoe was also damaged by flood waters, leaving 1,500 residents without running water.[14] In Port Arthur, twelve homes were reported flooded;[9] one house in the Lakeview neighborhood had 1 foot (0.30 m) of water inside.[15] Flood waters entered an oil pit at Port Neches, which sent at least 200 barrels of oil into the Neches River.[16]
Danielle also produced tides 2 to 3 feet (0.61 to 0.91 m) above normal, causing minor beach erosion along the Texas coast. Several boats and docks on Lake Buchanan were damaged.[1] A third fatality from the storm occurred when a fisherman's boat on Sabine Lake capsized, causing the man to die of a heart attack during rescue.[17] Danielle spawned several tornadoes in the state of Texas, one of which caused an estimated $1,500 (1980 USD) in damage to a storage barn in Galveston County on the Bolivar Peninsula.[18] Another touched down twice in Beaumont and overturned a mobile home at a mobile home park. After the storm, the American Red Cross opened storm shelters for residents forced out of their homes because of the flooding.[19] Due to adverse conditions, "hundreds" were left without electricity in Beaumont, Silsbee, Kountze, Hamshire, and Fannett.[20] In addition, then President of the United States Jimmy Carter declared Jefferson and Nolan counties as disaster area, allowing those areas to receive federal aid.[21] Damage in Jefferson County alone totaled to $2.7 million (1980 USD). Overall, Danielle caused two fatalities and between $25 million and $50 million (1980 USD) in damage within the state of Texas.[9][22]
Elsewhere
In the Gulf of Mexico, rough seas from Danielle caused a maintenance barge to capsize, washing all 11 crewmen overboard. A fatality occurred when one of the crewmen drowned, though the other ten were rescued by the United States Coast Guard. Additionally, the storm also caused a United States Coast Guard helicopter to crash into the sea due to high winds and lack of fuel, though all twelve crewmen survived.[9] Offshore, a barge encountered winds of 58 mph (93 km/h) with gusts up to 92 mph (148 km/h) and light rainfall.[2]
Danielle's effects on southern and eastern Louisiana was minimal. The state received moderate to heavy rainfall;[10] there, the highest rainfall total there was 2.23 inches (57 mm) in Houma.[23] Light rainfall was also reported in Oklahoma and Mississippi, with no areas reporting at least 3 inches (76 mm) of precipitation.[10]
