how many inches of rain did hurricane allison bring to houston
Tropical Storm Allison Combined with waves on top, areas of Galveston Island experienced a wall of water 8 feet (2.5 m) in height, creating overwash along the coastline. The storm caused winds of up to 43 mph (69 km/h) at the Galveston Pier. While Allison was stalling over Texas, it dropped very heavy rainfall across the state.[2] Minimal beach erosion was reported.[27] Flash flooding continued for days,[10] with rainfall amounts across the state peaking at just over 40 inches (1,033 mm) in northwestern Jefferson County. In the Port of Houston, a total of 36.99 inches (940 mm) was reported.[9] Houston experienced torrential rainfall in a short amount of time. The six-day rainfall in Houston amounted to 38.6 inches (980 mm).[28] Houston Hobby Airport received 20.84 inches of rain from June 5 to 10, 2001, while Bush Intercontinental Airport received 16.48 inches. [29] The deluge of rainfall flooded 95,000 automobiles and 73,000 houses throughout Harris County.[1] Tropical Storm Allison destroyed 2,744 homes, leaving 30,000 homeless with residential damages totaling to $1.76 billion (2001 USD, $2.29 billion 2012 USD).[28]
Hurricane Harvey The eighth named storm, third hurricane, and the first major hurricane of the 2017 Atlantic hurricane season, Harvey developed from a tropical wave to the east of the Lesser Antilles, reaching tropical storm status on August 17. The storm crossed through the Windward Islands on the following day, passing just south of Barbados and later near Saint Vincent. Upon entering the Caribbean Sea, Harvey began to weaken due to moderate wind shear and degenerated into a tropical wave north of Colombia early on August 19. The remnants were monitored for regeneration as it continued west-northwestward across the Caribbean and the Yucatán Peninsula, before redeveloping over the Bay of Campeche on August 23. Harvey then began to rapidly intensify on August 24, regaining tropical storm status and becoming a hurricane later that day. While the storm moved generally northwest, Harvey's intensification phase stalled slightly overnight from August 24–25; however, Harvey soon resumed strengthening and quickly became a major hurricane and attained Category 4 intensity later that day. Hours later, Harvey made landfall near Rockport, Texas, at peak intensity. Afterwards, rapid weakening ensued, and Harvey had downgraded to a tropical storm as it stalled near the coastline of the state, dropping torrential and unprecedented amounts of rainfall over the Lone Star state. On August 28, it emerged back over the Gulf of Mexico, strengthening slightly before making a third and final landfall in Louisiana on August 29. As Harvey drifted inland, it quickly weakened again as it became extratropical on September 1, before dissipating two days later.
