Category 1 Atlantic Hurricane in 1989

Hurricane Jerry caused minor damage in Texas and flash flooding in Kentucky and Virginia in October 1989. The fourteenth tropical cyclone, tenth named storm, and seventh hurricane of the season, Jerry developed from a tropical wave in the Bay of Campeche on October 12. Initially a tropical depression, the system moved north northwestward across the Gulf of Mexico and strengthened into Tropical Storm Jerry early on the following day. Jerry continuously deepened until October 14 and then maintained intensity while curving northeastward and briefly decelerating. Later that day, the storm re curved north northwestward. Jerry began to intensify on October 15 and soon became a Category 1 hurricane on the Saffir–Simpson hurricane wind scale. Early on October 16, Jerry made landfall on Galveston Island, Texas with winds of Less than six hours later, Jerry weakened to a tropical storm and then a tropical depression shortly thereafter. Late on October 16, Jerry was absorbed by a frontal system while situated over southwestern Arkansas. Storm surge and rough surf along the coast of Texas destroyed a 20 mile (32 km) section of Texas State Highway 87, which was never repaired. Due to strong winds, about 52,000 homes and businesses were left without electricity, most of them in the Galveston area. Many homes, businesses, and buildings were inflicted damage because of strong winds and three tornadoes spawned by the storm. Despite the issuance of a hurricane warning just eight hours prior to landfall, Jerry caused only three fatalities in Texas, possibly due to the storm's small size; a car fell over the Galveston Seawall, killing its three occupants. Minor wind and coastal flood damage was reported in Louisiana. Jerry and its remnants brought flash flooding to portions of the Upland South, particularly in the states of Kentucky, Virginia, and West Virginia. In eastern Kentucky, hundreds of homes were flooded and many bridges, culverts, and roads were washed out; this left hundreds of residents stranded. Damage in Kentucky reached at least $5 million. Similar impact occurred in Virginia; with $3.4 million (1989 USD) in damage in Buchanan County. In West Virginia, overflowing rivers in the western portions of the state forced hundreds to evacuate. Throughout the United States, Jerry resulted in about $70 million in damage.

A tropical wave emerged into the Atlantic Ocean from the coast of northwest Africa on September 23. No additional signs of tropical cyclogenesis were observed as the tropical wave crossed the Atlantic Ocean or the Caribbean Sea. The tropical wave decelerated upon reaching the Yucatán Peninsula, where it became a broad low pressure area, based on surface pressure fields and convective motions indicated in satellite imagery. While emerging into the Bay of Campeche on October 12, the intensity of the low was estimated via Dvorak technique. At 1900 UTC on October 12, a reconnaissance aircraft flight confirmed an atmospheric circulation, and the system was then classified as Tropical Depression Fourteen. However, post analysis indicates that the depression developed seven hours earlier, while located about 230 mile (370 km) east northeast of Veracruz, Veracruz. While moving north northwestward, satellite and reconnaissance aircraft reports indicated the depression strengthened into Tropical Storm Jerry early on October 13. Jerry then gradually intensified and moved northward between Early on October 14, the storm turned to the north northeast and decelerated in response to an approaching mid to upper level trough. Increasing upper level wind shear temporarily limited further intensification. However, after a mid to upper level cut off low pressure area moved southward, the upper level outflow pattern became more favorable, causing Jerry to resume strengthening. The cut off low then forced Jerry to re curve north northwestward, while stronger steering currents and a high pressure ridge increased the storm's forward motion to more than While approaching the Gulf Coast of the United States, deep convection began to develop near the center, and by 1800 UTC on October 15, Jerry strengthened into a Category 1 hurricane. The storm strengthened slightly further before making landfall on Galveston Island near Jamaica Beach, Texas with winds of at 0030 UTC on October 16. Jerry's landfall is among the latest dates in the satellite era that a hurricane struck the upper Texas coast. After moving inland, the storm then accelerated while turning toward the north and then north northeastward. At 0600 UTC on October 16, Jerry weakened to a tropical storm and to a tropical depression about six hours later. Late on October 16, the cyclone was absorbed by a frontal system over southwestern Arkansas.

Jerry was an unpredictable storm as the strengthening before landfall and the continuation to the northwest were not anticipated. Equipment failure meant that data was not readily available. The National Hurricane Center forecast model was also disabled, throwing the accuracy of Jerry's track off. Tropical cyclone warnings and watches began early on October 14, with a hurricane watch for Port Arthur, Texas to the mouth of the Mississippi River in Louisiana. At 2200 UTC later that day, a tropical storm watch was issued for the entire coast of Louisiana. Another tropical storm watch was posted from Port O'Connor, Texas to Morgan City, Louisiana at 1200 UTC on October 15. Due to the unpredictability of the storm, a hurricane warning was issued from Freeport, Texas to Intracoastal City, Louisiana at 1600 UTC, only eight hours prior to landfall. In Louisiana, approximately 8,000 people evacuated – 1,000  from Grand Isle and 7,000 others from Cameron Parish. Jerry caused light beach erosion along the Texas coast. The storm destroyed a 20 mile (32 km) section of Texas State Highway 87, between High Island and Sabine Pass. In Galveston County, abnormally high astronomical tides and rough surf from Jerry resulted in coastal flood damage. Beach erosion was reported, while some sand dunes were flattened. On the western end of Galveston Island, beachfront roads were inundated and covered with debris, glass, and boards. In Brazoria County, high tides caused minor road damage in Surfside Beach. Storm surge in Chambers County caused coastal flooding in Anahuac. Three people were killed when their car was either blown or washed off the Galveston Seawall during the storm. The eye of the Hurricane went directly over Kemah where waterfront businesses suffered considerable damage, including restaurants, boat docks, and bait stands. Property losses in the city of Kemah was estimated to have reached $2 million. In the upper end of Galveston Bay in Harris County, businesses in low lying areas were affected by coastal flooding. There were three tornadoes in the county, the first of which unroofed some buildings in Galveston. The second tornado, also touching down in Galveston, inflicted roof damage to many businesses, homes, and apartment complexes. The third tornado, spawned in League City, toppled several trees and a flag pole. In Chambers County a tornado near Kemah inflicted damage to a beach house. Another tornado in the county spawned in downtown Baytown shattered windows at a hospital, a mall, and store windows. In Polk County, a small tornado caused minor damage, totaling $10,000.

In Louisiana, tides ranging from above normal lashed the coast. However, coastal flooding damage was minimal. Gusty winds in the northwestern portion of the state downed some trees and power lines. Due to the impact from flooding in eastern Kentucky, President George H. W. Bush declared Clay, Floyd, Jackson, Knott, Knox, Leslie, Letcher, Magoffin, Owsley, Perry and Pike counties as disaster areas. Heavy rains in West Virginia overflowed the Tug Fork and Guyandotte rivers. About 150 homes were evacuated in Matewan, where the Tug Fork River crested at 6 feet (2 m) above its banks. Farther south in Williamson, the river overflowed its banks by about 3 feet (1 m). On October 19, Governor of West Virginia Gaston Caperton toured flood ravaged areas of the state, including Mingo and Logan counties. Heavy rainfall extended eastward into extreme western Virginia. In northern Buchanan County, flash flooding destroyed or heavily damaged numerous businesses and homes. Additionally, many private bridges were swept away and more than 100 roads were inundated. Approximately 30 families were evacuated in the Hurley area, where up to of precipitation was observed. Damage in Buchanan County totaled $3.4 million.
