Former Hurricane Henriette weakened back to a tropical storm over the Central Pacific Ocean north of Hawaii on Tuesday. At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Henriette was located at latitude 32.8°N and longitude 161.6°W which put the center about 825 miles (1330 km) north-northwest of Honolulu, Hawaii. Henriette was moving toward the northwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 994 mb.
Former Hurricane Henriette weakened back to a tropical storm over the Central Pacific Ocean north of Hawaii on Tuesday. Henriette moved into a region of drier air that is northwest of Hawaii. The drier air was pulled around the southern side of Tropical Storm Henriette. The drier air affect the structure of Henriette.
Thunderstorms were still occurring near the center of Tropical Storm Henriette. Thunderstorms were also still occurring in bands in the eastern and northern sides of Henriette’s circulation. Bands in the southern and western sides of Tropical Storm Henriette consisted primarily of showers and lower clouds.
The circulation around Tropical Storm Henriette was small. Winds to tropical storm force extended out 80 miles (130 km) from the center of Henriette’s circulation.
Tropical Storm Henriette will move through an environment that will become more unfavorable for intensification during the next 24 hours. Henriette will move over water where the Sea Surface Temperatures are near 26°C. It will move under the eastern side of an upper level low that is northwest of Hawaii. The upper level low will produce southerly winds that will blow toward the top of Henriette’s circulation. Those winds will cause the vertical wind shear to increase. In addition, Henriette will continue to move through the region of drier air northwest of Hawaii. More vertical wind shear and the effects of the drier will cause Tropical Storm Henriette to continue to weaken during the next 24 hours.
Tropical Storm Henriette will move around the southwestern part of a high pressure system over the central North Pacific Ocean. The high pressure system will steer Henriette toward the northwest during the next 24 hours. On its anticipated track, Tropical Storm Henriette will continue to move farther away from Hawaii.
