Not only was Harvey forecast to become a hurricane by Thursday evening, but it was expected to strengthen and make landfall as a major hurricane (Category 3 or higher) on Friday (see forecast). On Thursday August 24 th, Harvey's impact on the Middle and Upper Texas Coast seemed almost certain and potentially devastating. By Wednesday evening, Harvey was forecast to make landfall as a hurricane somewhere over the Texas Coast. However, with wind shear in the Western Gulf of Mexico weakening, Tropical Storm Harvey was intensifying quickly. Initially, NHC believed Harvey would become either a strong tropical storm or a Category 1 hurricane before making landfall somewhere between Brownsville (early Friday morning) and Houston (early Saturday morning), with the most likely location near the Rockport area late Friday night. At 10 AM CDT Wednesday August 23 rd, Tropical Depression Harvey reformed. With very warm waters in the Bay of Campeche and the Western Gulf of Mexico, the National Hurricane Center (NHC) was fairly confident that the remnants of Harvey would reform into a tropical cyclone. The genesis of Harvey from a Depression to a Major Hurricane: 542 PM CDT 08/23/17 to 657 PM CDT 08/26/17 (GOES-16 data is non-operational.) Although there was some potential for the remnants of Harvey to reorganize into a tropical cyclone, a tropical cyclone failed to form as the remnants of Harvey moved into the Yucatan Peninsula on Tuesday morning, August 22 nd. Tropical Storm Harvey impacted the Windward Islands on Friday, August 18 th, entering the Eastern Caribbean Sea as a minimal tropical storm, and eventually weakening to a tropical wave late Saturday evening. Tropical Storm Warnings were issued that afternoon for Martinique, St. However, by Thursday August 17 th, the National Hurricane Center began issuing advisories and forecasts on Tropical Cyclone Nine Thursday morning, and Tropical Storm Harvey Thursday afternoon. For a few days on its westward track, "Harvey" remained disorganized, and there was some uncertainty whether the low would become a tropical cyclone. However, this low stayed more on a westward course as it moved over the open Atlantic Ocean toward the Eastern Caribbean Sea. At first, it was thought the wave and the low pressure area would have a more west-northwest track, threatening the Lesser Antilles.
The birth of Harvey occurred on Sunday August 13 th, 2017 as a tropical wave emerged off the west coast of Africa, eventually merging with a broad area of low pressure near the Cabo Verde Islands. KCRP Radar Loop - 500 AM CDT August 25 through 912 AM CDT August 26, 2017 After impacting the Yucatan Peninsula earlier in the month as a tropical storm, Harvey moved into the warm waters of the Gulf of Mexico late on Tuesday August 22 nd. Harvey exploded rapidly from a tropical depression to a major hurricane in around 40 hours. Well, the "when" happened on August 25 th 2017, when Harvey made landfall along the Middle Texas Coast. The last hurricane to do so was Celia back on August 3 rd, 1970. Over the past several years, meteorologists in South Texas (and other areas) have stated "it's not a matter of if but when" a major hurricane would strike the Middle Texas Coast.
