Rain Destruction: Tropical cyclones, storms and depressions can sometimes carry with them large amounts of rainfall. Tropical Storm Allison caused at least 41 deaths and $4.8 billion in damage in the Houston area, and is only the latest example of such flooding. Tropical Storm Claudette in 1979 deposited over 40 inches of rain on Alvin, Texas in 24 hours, causing extensive flooding and damage. The heavy rainfall sometimes associated with these storms can cause flash-floods, which carry with them swift currents in hills such as in east Texas and the Hill Country. Record-breaking rainfalls in Texas and the United States have largely been associated with remnants of tropical cyclones. The average rainfall in most hurricanes is 1 to 5 inches. Table 6 shows some of the rainfall amounts in some Texas storms.

Tornado Destruction: The hurricane brings with it many significant weather features such as thunderstorms and squalls, but tornadoes also develop. Most of the tornadoes associated with tropical systems seem to occur in the right-front quadrant. In Texas, the record for the most tornadoes generated was during Hurricane Beulah in 1967, with at least 115 documented tornadoes. The tornado in a hurricane is smaller and has a shorter track than the typical Great Plains tornado. Table 7 shows the number of tornadoes associated with various Texas hurricanes.

Electric Shock: Another major problem during a storm event is downed power lines in flooded waters. Several deaths have been caused in past hurricanes from electric shock. Entering a flooded home where the main power has not been turned off can also present a risk of death from electric shock.
