Hurricane Claudette was the third tropical storm and first hurricane of the 2003 Atlantic hurricane season. A fairly long-lived July Atlantic hurricane, Claudette began as a tropical wave in the eastern Caribbean Sea. It moved quickly westward, brushing past the Yucatán Peninsula before moving northwestward through the Gulf of Mexico. Claudette remained a tropical storm until just before making landfall in Port O'Connor, Texas, when it quickly strengthened to a strong Category 1 hurricane on the Saffir-Simpson Hurricane Scale. Forecasting of its path and intensity was uncertain throughout its lifetime, resulting in widespread and often unnecessary preparations along its path.

Claudette was the first hurricane to make landfall in July in the United States since Hurricane Danny in the 1997 season. The hurricane caused one death and moderate damage in Texas, mostly from strong winds, as well as extensive beach erosion. Because of the damage, President George W. Bush declared portions of South Texas as a Federal Disaster Area, allowing the affected citizens to apply for aid. Claudette also caused significant rainfall and minor damage in the Mexican state of Quintana Roo as a tropical storm, as well as minor damage on Saint Lucia before developing into a tropical cyclone.

[edit] Storm history

A tropical wave moved off the coast of Africa on July 1. It steadily organized as it moved westward, and resembled a tropical depression by July 7. However, surface reports and reconnaissance aircraft indicated the system did not have tropical characteristics, and remained simply a low-pressure system. The wave produced tropical storm-force winds as it moved through the Lesser Antilles on July 8, but did not acquire tropical characteristics until it reached the eastern Caribbean Sea. Because it had tropical storm-force winds, the system was upgraded immediately to Tropical Storm Claudette after it developed a low-level circulation later on July 8.^[1]

By early on July 9, while south of Puerto Rico, Claudette quickly strengthened over the warm waters of the Caribbean, and its strongest winds were just shy of the threshold for hurricane intensity. Possibly due to its fast forward motion, the storm became disorganized and weakened. Conditions briefly became more favorable over the western Caribbean, and Claudette reached hurricane status for six hours on the 10th. Soon after, the storm encountered unfavorable upper-level winds and weakened back into a tropical storm. In response to a break in the subtropical ridge—a high-pressure ridge that often prevents tropical systems from moving northward—it turned to the west-northwest. Claudette made its first landfall at Puerto Morelos on the Yucatán Peninsula on the 11th as a tropical storm with 60 mph (95 km/h) winds.^[1]

Claudette wobbled to the northwest over the Gulf of Mexico and gradually restrengthened. Upper-level winds steadily decreased, and Claudette again became a hurricane late on July 14. Just prior to landfall, it strengthened quickly and picked up its forward motion in a more westerly direction striking Port O'Connor, Texas on July 15 as a Category 1 hurricane on the Saffir-Simpson Hurricane Scale with 90 mph (145 km/h) winds. Residents along and inland of the central Texas coast were caught off guard both by its intensity and its time of arrival. The hurricane was projected to make landfall in the evening hours of July 15, but instead came ashore before noon.^[2] Furthermore, some initial estimates suggested that Claudette had reached Category 2 status, with sustained winds of up to 100 mph (160 km/h); these were based on unofficial observations which were not backed up by official data.^[1]

As slow as Claudette was to strengthen, it was also slow to dissipate over land. Inland hurricane warnings were issued for several counties away from the coastline and winds gusted to 83 mph (134 km/h) at Victoria Regional Airport.^[2] It maintained tropical storm intensity for over 24 hours after landfall, a rarity for such a weak storm; most tropical systems weaken rapidly after landfall, as they are separated from the warm waters that power them. The storm finally lost its low-level circulation early on July 17 over Chihuahua, although its rainfall and upper-level circulation continued into the Pacific Ocean.^[1]

[edit] Preparations

Mexican officials issued a tropical storm warning 37 hours prior to the storm's landfall between Chetumal and Cabo Catoche, Quintana Roo. The warning was upgraded to a hurricane warning about a day before landfall, but was downgraded when Claudette weakened just 13 hours prior to its landfall in the Yucatán Peninsula.^[1] The Mexican government declared a state of emergency in the projected path of the storm, and declared an evacuation order for 1,500 citizens in Quintana Roo. There, residents remained calm during the evacuation.^[3] Tourists left nightclubs for supermarkets to stock up, among other items, beer, a commodity that was banned at midnight. Schools were set up as shelters, while police forced tourists to remain in their hotels.^[4]

On July 13, two days prior to Claudette's eventual landfall, the National Hurricane Center issued a hurricane watch between Brownsville and Port O'Connor, Texas. By the next day, a hurricane warning existed from Baffin Bay to High Island, Texas, while a tropical storm warning extended from High Island to Intracoastal City, Louisiana. When it became apparent that Louisiana would not be affected significantly by the storm, the state's tropical storm warnings were cancelled.^[1] In Texas, Galveston County officials issued a voluntary evacuation for western Galveston Island and Jamaica Beach 24 hours prior to Claudette's projected landfall. The Emergency Phone Notification System notified citizens in the evening to avoid evacuating during the night. Many citizens heeded the evacuation suggestion, some of whom remembered the flooding from Tropical Storm Frances five years before.^[5] Claudette's consistent variation in its path caused uncertainty over the strength and location of its final landfall, and because of this, no shelters were open during the passage of Claudette, forcing citizens to ride out the hurricane.^[1][6]

Hurricane Claudette also affected the oil industry. Chevron, Shell Oil, Marathon Oil, Unocal Corporation, and Anadarko Petroleum Corporation all limited production and evacuated many of their workers. Chevron, which evacuated more than 1,800 workers in the Gulf of Mexico, lost about 30% of its daily production, which included 92 million barrels (14,600,000 m³) of oil and 236 million cubic feet (6.7 million cubic meters) of natural gas each day. Shell limited their crude production to about 15% of their pre-storm levels, and daily natural gas production dropped 96%. Similarly, Marathon's oil output during the storm shrunk to 2% of normal production, and its natural gas output dropped to 1.5%. Unocal temporarily closed 23 rigs, and Anadarko shut down 11 rigs for the storm's duration.^[7] In total, the storm shut down 21% of the Gulf of Mexico's crude oil production and 18% of its natural gas output.^[8]

[edit] Impact

Outside of Texas, Hurricane Claudette caused little damage due to its low intensity. In total, damage estimates rose to $180 million (2003 USD, $198 million 2006 USD), and the storm caused one direct and two indirect deaths. One of the indirect deaths occurred from a man having a heart attack while surfing in the eastern Gulf of Mexico.^[1]

[edit] Caribbean Sea

As a tropical wave, Claudette dropped torrential rainfall and brought strong winds to the island of Saint Lucia. The George F. L. Charles Airport in Castries reported a wind gust of 52 mph (84 km/h), while other parts of the island experienced nearly horizontal rainfall from the gusts. On the northern and eastern portions of the island, the strong winds ripped off roofs and downed trees across roadways.^[9] Overall, damage was light, and amounted to $1.1 million (2003 USD, $1.2 million 2006 USD).^[10]

In the Dominican Republic, the outer bands of the storm caused moderate rainfall of up to 3 inches (80 mm) in Santo Domingo. Winds gusted up to 45 mph (70 km/h), knocking down trees, sign posts, and iron roofs. Also, flooding in metropolitan areas blocked traffic for cars and pedestrians. Banana and other fruit plantations in the southwestern portion of the country experienced severe damage, although exact damage totals are unknown.^[11]

On Jamaica, the storm caused wind gusts of 45 mph (70 km/h) in Montego Bay.^[1] Forecasters predicted high tides, strong waves, and up to 6 inches (150 mm) of rain on the island, although exact post-storm totals are not known.^[12] Many fishermen moved their boats from the water to safety, while a cruise line diverted three ships away from Claudette's path.^[13]

In the Cayman Islands, where the storm remained 165 miles (265 km) away at its closest point, rainfall totals ranged from 1–3 inches (25–75 mm).^[1] On the south side of Grand Cayman, Claudette caused wave heights of around 10 feet (3 m), while the western side received little precipitation. Also on Grand Cayman, the storm caused winds of 35–40 mph (55–65 km/h), causing minor tree damage but little else.^[14]

On Mexico's Yucatán Peninsula, Claudette lashed strong waves against the coastline at Cancún, but overall caused light damage.^[15] While crossing the peninsula, the storm dropped moderate rainfall, including a total of 3.22 inches (81 mm) in Cancún.^[1] Winds were moderate, causing the Cancún International Airport to delay several flights, though there were no cancellations. Overall, Claudette sank a few small boats and flooded a few streets in Cancún, though damage was minor in the Yucatán Peninsula.^[15]

[edit] Texas

Upon making landfall on the central Texas coast, Claudette's storm surge reached a maximum height of 5.3 feet (1.6 m) in Galveston. Freeport reported a "storm tide"—the overall rise of water over the mean low tide—of 9.15 feet (2.8 m). Claudette produced moderate rainfall across southern Texas, peaking at 6.5 inches (165 mm) in Tilden. In Matagorda, the local weather station measured winds of 75 mph (120 km/h)—the only official report of hurricane-force winds along the coastline. However, several offshore oil rigs reported winds of up to 90 mph (120 km/h), and one unofficial reading in Seadrift indicated winds of 96.6 mph (156 km/h). This report would suggest the storm was a low-end Category 2 hurricane, though this contradicted Hurricane Hunters' data, which pointed to a storm of a lesser intensity.^[1]

Severe beach erosion occurred from High Island to Freeport, though large geo-tubes reduced the erosion on Galveston Island and the Bolivar Peninsula.^[16] The outer bands of the hurricane spawned two tornadoes. One was an F1 on the Fujita scale that caused damage to several buildings in Palacios, and the other damaged homes in Port Lavaca.^[1]

Widespread flooding and gusty winds destroyed 204 houses along the southeast Texas coastline, most of which occurred in Matagorda County. In addition, the winds damaged 1,407 homes, with 144 of them being severely damaged. The wind also affected 147 businesses, of which 64 were either destroyed or severely damaged.^[16] Strong winds downed numerous power lines, leaving around 74,000 residents without power in the immediate aftermath.^[17] Overall, Claudette caused $180 million (2003 USD, $198 million 2006 USD) in damage in Texas and one death from a fallen tree during the storm. Also, the storm was indirectly responsible for a death when a tree fell on a person in the aftermath of the storm.^[1]

[edit] Aftermath

On July 17, President George W. Bush declared 18 south Texas counties as a federal disaster area. Within 2 months of the storm, over 15,000 citizens registered for assistance.^[18] The government approved $34.8 million in aid, of which nearly half went to basic house repairs. FEMA provided 75% of the $1.35 million debris removal cost, with the other 25% being covered through local agencies.^[19] FEMA also provided $1.26 million to repair geo-tubes on the Bolivar Peninsula in Galveston County. The geo-tubes, which protect buildings along coastal areas, were severely damaged by the hurricane.^[20]

In western Texas, heavy rainfall of up to 5 inches (130 mm) temporarily turned the typically arid landscape into an area rife with flowers. The rainfall restored the flow of the Rio Grande at Big Bend National Park, which had ceased in the area due to lack of rainfall. In addition, it increased the water level in the Amistad National Recreation Area to 4 feet (1.2 m).^[21]

The World Meteorological Organization did not consider the damage to be significant enough to warrant retiring the name Claudette, and as a result it will be used again in the 2009 season.
