Tropical Storms Hernan and Iselle formed west of Mexico.\u00a0 At 11:00 a.m. EDT on Thursday the center of Tropical Storm Hernan was located at latitude 19.1\u00b0N and longitude 106.2\u00b0W which put it about 95 miles (155 km) south-southwest of Cabo Corrientes, Mexico.\u00a0 Hernan was moving toward the north-northwest at 5 m.p.h. (8 km\/h).\u00a0 The maximum sustained wind speed was 45 m.p.h. (75 km\/h) and there were wind gusts to 60 m.p.h. (95 km\/h).\u00a0 The minimum surface pressure was 1001 mb.<\/p>\n
The circulation around Tropical Storm Hernan was not well organized.\u00a0 An upper level ridge over the southwestern U.S. and northern Mexico was producing northeasterly winds which were blowing toward the top of Hernan.\u00a0 Those winds were causing strong vertical wind shear.\u00a0 As a result of the shear, the stronger thunderstorms were occurring in bands in the southern part of the circulation.\u00a0 Bands in the other parts of Tropical Storm Hernan consisted primarily of showers and lower clouds.\u00a0 Winds to tropical storm force extended out 100 miles in the southern half of Hernan.\u00a0 Winds in the northern half of the circulation were blowing at less than tropical storm force.<\/p>\n
Tropical Storm Hernan will move through an environment unfavorable for intensification during the next several days.\u00a0 Hernan will move over water where the Sea Surface Temperature is near 29\u00b0C.\u00a0 So, there will be plenty of energy in the upper ocean to support intensification.\u00a0 However, the upper level ridge will continue to cause strong vertical wind shear, which will inhibit potential intensification.\u00a0 Tropical Storm Hernan is likely to weaken on Friday when it moves over colder water.\u00a0 Hernan could approach the southern end of Baja California on Friday.<\/p>\n
At 11:00 a.m. EDT on Thursday the center of Tropical Storm Iselle was located at latitude 17.0\u00b0N and longitude 115.8\u00b0W which put it about 560 miles (900 km) southwest of the southern tip of Baja California.\u00a0 Iselles was moving toward the northeast at 5 m.p.h. (8 km\/h).\u00a0 The maximum sustained wind speed was 45 m.p.h. (75 km\/h) and there were wind gusts to 60 m.p.h. (95 km\/h).\u00a0 The minimum surface pressure was 1001 mb.<\/p>\n
The circulation around Tropical Storm Iselle was also not well organized.\u00a0 It was being sheared by the same upper level ridge that was causing strong vertical wind shear over Tropical Storm Hernan.\u00a0 Most of the thunderstorms in Iselle were also occurring in the southern half of the circulation.\u00a0 Tropical storm force winds extended out 100 miles from the center in the southern half of Tropical Storm Iselle.\u00a0 Iselle will also move through an environment unfavorable for intensification.<\/p>\n","protected":false},"excerpt":{"rendered":"
