Hurricane season=2007 Atlantic hurricane season Hurricane Humberto was a minimal hurricane that formed and intensified faster than any other
tropical cyclone on record before landfall. Developing on September 12, 2007, in the northwesternGulf of Mexico , the cyclone rapidly strengthened and struckHigh Island, Texas with winds of about 90 mph (150 km/h) early on September 13. It steadily weakened after moving ashore, and on September 14 it began dissipating over northwestern Georgia as it interacted with an approachingcold front .Damage was fairly light, estimated at approximately $50 million (2007 USD). Precipitation peaked at 14.13 inches (358.9 mm), while wind gusts to 85 mph (137 km/h) were reported. The heavy rainfall caused widespread flooding, which damaged or destroyed dozens of homes, and closed several highways. Trees and power lines were downed, knocking out power to hundreds of thousands of costumers. The passage of the hurricane caused one fatality in the State of Texas. Additionally, as the storm progressed inland, rainfall was reported throughout the
Southeast United States .Meteorological history

The path of the eye continued northeastward and passed over Port Arthur, Nederland, Port Neches, Groves, and
Bridge City, Texas at Category 1 hurricane strength.

Texas
A few hours prior to its development, outer rainbands from the depression began moving over portions of the Texas coast. Heavy rainfall from intense thunderstorms caused minor flooding as they crossed the coastline during the subsequent days;cite web|author=Blood, Overpeck, Lichter|year=2007|title=Hurricane Humberto Post-Tropical Cyclone Report|publisher=Houston, Texas National Weather Service|accessdate=2007-09-19|url=http://www.srh.noaa.gov/data/warn_archive/HGX/PSH/0919_202212.txt] precipitation in the state peaked at 14.13 inches (358.9 mm) at East Bay Bayou, the highest recorded rainfall total in association with the hurricane. Sustained winds peaked at 69 mph (112 km/h) with gusts to 85 mph (137 km/h) at
Sea Rim State Park ; theNational Weather Service estimates gusts exceeded 90 mph (145 km/h) in southwestern Jefferson County and extreme southeastern Chambers County.cite web|author=National Weather Service|year=2007|title=Hurricane Humberto Winds & Lowest Pressures|accessdate=2007-09-19|url=http://www.srh.weather.gov/lch/tropical/humbertowinds.php] Upon moving ashore, Humberto produced a minor storm surge in the state, peaking at 2.86 feet (0.87 m) atRollover Pass ; the combination of surge and waves resulted in light beach erosion.Hurricane Humberto left 10 homes completely destroyed in Galveston County, with an additional 19 severely damaged in the county; several homes received minor shingle damage, and road closures left about 5,000 houses isolated in the county. The combination of saturated grounds and strong winds uprooted many trees and downed power lines across the path of the hurricane, with at least 50 high voltage transmission poles blown down or seriously damaged; over 120,000 power customers in Orange and Jefferson counties lost power,cite web|author=Landreneau, Shamburger, Erickson, and Rua|year=2007|title=Hurricane Humberto Post-Tropical Cyclone Report|publisher=Lake Charles, Louisiana National Weather Service|accessdate=2007-09-20|url=http://www.srh.noaa.gov/data/warn_archive/LCH/PSH/0920_030551.txt] with 118,000

Additionally, several roadways were flooded. The passage of the hurricane caused one fatality in the state; a Bridge City man was killed when his carport crashed on him outside his house. Overall damage estimates were about $50 million.Oil production was slowed as a result of Humberto, as at least four refineries—the Valero plant in Port Arthur and the
ExxonMobil ,Total SA andMotiva Enterprises LLC plants in Beaumont—were halted due to the loss of power. Oil prices rose above $80 a barrel in intraday trading on September 12 as a result, ending the next day at a record high of $80.09 a barrel.

Tracking through the state as a weakening tropical storm, Humberto produced light to moderate winds across southwestern Louisiana. Gusts officially peaked at 43 mph (69 km/h) in the state, although an unofficial reading of 55 mph (89 km/h) was reported in Vinton. Heavy rainfall occurred across the area, reaching a peak of 8.25 inches (210 mm) in DeRidder.cite web|author=National Weather Service|year=2007|title=Hurricane Humberto Rainfall|accessdate=2007-09-20|url=http://www.srh.weather.gov/lch/tropical/humbertorainfall.php] The rainfall triggered minor river flooding, and the
Vermilion River in Lafayette reached a crest of 0.94 feet (0.29 m) above flood stage. Storm surge was minor in the state, peaking at 2.13 feet (0.65 m) in Cypremont Point;cite web|author=National Weather Service|year=2007|title=Hurricane Humberto Storm Surge and River Levels|accessdate=2007-09-20|url=http://www.srh.weather.gov/lch/tropical/humbertostormsurge.php] no beach erosion was reported.Widespread freshwater flooding occurred in Beauregard Parish, leaving homes in DeRidder flooded. High water across the southwestern portion of the state resulted in the closure of several roadways, including
U.S. Route 171 and various state highways. Isolated wind damage was reported, particularly near the Texas border, with some trees and power lines blown down. A total of about 13,000 power customers lost electricity in southwestern Louisiana. After the circulation dissipated, the remnants of Humberto spawned several tornadoes across portions ofSouth Carolina andNorth Carolina and caused widespread damage to portions of three counties in the central part of the state. Numerous tornadoes were reported, [cite web|author=Raleigh, North Carolina National Weather Service|year=2007|title=Hurricane Humberto Special Weather Statement|accessdate=2007-12-25|url=http://www.erh.noaa.gov/rah/news/content/RDUPNSRAH.20070914.html] though none caused any injuries.

Hours after Humberto made landfall, Rick Perry declared Galveston, Jefferson, and Orange counties as disaster areas, which allocated state resources to assist the affected residents. The governor applied for a presidential disaster declaration on September 21.

Federal Emergency Management Agency (FEMA) teams assessed the hurricane damage in the three most affected counties. Because the damage from Hurricane Humberto was not severe, the name "Humberto" was not retired, and is on the list of names to be used during the2013 Atlantic hurricane season .cite web|title=Worldwide Tropical Cyclone Names|year=2007|publisher=National Hurricane Center|accessdate=2008-02-19|url=http://www.nhc.noaa.gov/aboutnames.shtml]See also
