August and so far September as well have generated plenty of tropical cyclone activity worldwide. Both the Atlantic and Western Pacific have been particularly active basins.
Currently on the larger Atlantic basin we have former tropical storm HERMINE, now a tropical depression, over central Texas to the NW of Austin on a track toward Abilene and Wichita Falls generating copious rain for the last couple of days, which have caused flash floods and plenty of problems over a wide swath of Lone Star State.
In the Caribbean just south off the coast of Hispaniola the remnants of GASTON appear to be regrouping as the system moves westward while generating large amounts of rain over both the Dominican Republic and Haiti. Far behind, some 2000 miles, in Hurricane Alley there is a large tropical wave to the SW of the Cape Verde Islands moving westward. Other minor tropical waves are over equatorial Africa also moving westward along the always busy ‘assembly line’.
Over in the western Pacific there is Tropical Storm ELEVEN just SW of Taiwan moving toward mainland China and to the north weakening tropical storm MALOU is over central Japan to the north of Kyoto and west of Tokyo tracking toward the northeast. There is a triangular region from just east of the Philipinnes to northern Vietnam and the Korean peninsula that has seen constant tropical cyclone activity over the past several weeks.
An area of low pressure that had developed over the extreme southwestern Gulf in the Bay of Campeche is now Tropical Storm HERMINE, the 8th-named storm of the 2010 Atlantic hurricane season. Hermine is moving north by northwest toward a projected landfall in northeastern Mexico. The Gulf of Mexico has seen quite a bit of tropical cyclone activity already this season, and the Bay of Campeche has had recurrent generation of disturbed weather cells, one of which eventually spawned Hermine.
After a slow start during which the 2010 season produced only two named storms in June and July, the month of August saw five named-storms: Colin, Danielle, Earl, Fiona and Gaston and a number of tropical waves that flared-up to dissipate afterwards. During the first few days of September Earl came close to the USA Atlantic coastline causing some coastal flooding and damage without making landfall, as it continued moving toward Canada’s maritime provinces and the North Atlantic; Fiona followed a track parallel to Earl but farther out over the Atlantic to pass close to Bermuda, and Gaston rapidly flared-up from a tropical wave to tropical storm strength to quickly fizzled out.
Over the last couple of days however there has been some reactivation leading to tropical storm Hermine and a strengthening of Gaston’s remnants to the east of the Leeward islands, while a tropical wave has entered Hurricane alley in the eastern Atlantic and several tropical waves march westward over equatorial Africa
