NASA’s QuikScat satellite helped forecasters locate Kevin’s center earlier today and QuikScat’s wind data revealed that he’s weakening. QuikScat uses microwave technology to “see through clouds” and also saw Kevin’s mid-level circulation appears to be decoupling from his low-level center.

Think of how when you push the top of “Slinky” wire toy to one side of it, and that’s what’s happening to Kevin’s center. It means the storm’s mid-level center is leaning away from the bottom center, and that’s a sign of weakening.

At 5 a.m. EDT on Monday, August 31, Tropical Storm Kevin had sustained winds near 40 mph, and was 895 miles west-southwest of the southernmost tip of Baja California, near 16.3 north and 121.7 west. Kevin was moving north-northeast near 6 mph, with a minimum central pressure of 1005 millibars. Late last night , Sunday, August 30, NASA’s QuikScat satellite flew over Kevin and confirmed that 40 mph winds “were confined to the deep convection over the northwestern quadrant of the storm.”

NASA’s Aqua satellite also flew over Kevin, and the Atmospheric Infrared Sounder (AIRS) captured an infrared image of Kevin earlier today. The image, which reveals cloud temperatures, showed that Kevin’s clouds were not as cold as they were over the last few days, revealing a weakening storm. Colder cloud temperatures mean higher clouds, and more powerful thunderstorms. The AIRS image showed that Kevin is losing his punch.

The National Hurricane Center expects Kevin to weaken further and drop to tropical depression status later today.

Weekends and tropical cyclones have gone together this hurricane season, and this weekend, Danny is dying in the Atlantic, while Jimena has exploded in fast development in the eastern Pacific Ocean.

Danny is in the process of being absorbed by an extra-tropical low pressure area over North Carolina, and has lost his punch in terms of sustained winds. Danny has been downgraded to a tropical depression this morning, Saturday, August 29. However, he’s still packing a lot of heavy rain, and bringing dangerous surf along the U.S. east coast from the Mid-Atlantic to the Northeast into Canada.

Danny’s heavy rainfall is mostly located to the north and northeast of the storm, as evidenced in NASA satellite data. As he continues merging with the extra-tropical low pressure system today, his center will stay off-shore and keep moving north. Ahead of his center, heavy rains will pour over eastern Long Island, eastern Massachusetts, coastal New Hampshire and Maine, before moving into Nova Scotia, Canada.

When the Tropical Rainfall Measuring Mission satellite (managed by NASA and JAXA) flew over tropical storm Danny yesterday, August 28, it revealed that only moderately heavy rain was occurring then in an area northeast of Danny’s center of circulation. That also holds true today, August 29 as Danny is now raining on the northeastern U.S. On the radar, Danny’s rainfall looks like a large “V” shape entering New England.

Dangerous surf is the other issue Danny is causing. Beachgoers should not venture into the ocean, as Tropical Depression Danny is stirring up surf 3-5 feet high in the mid-Atlantic. Surf is much higher, as much as 6-10 feet, near Long Island, N.Y., and coastal Rhode Island, Connecticut, and south and east-facing Cape Cod, Massachusetts.

At 5 a.m. EDT today, Saturday, August 29, the National Hurricane Center in Miami, Fla. issued its last advisory on Tropical Depression Danny. At that time, Danny’s remnants had sustained winds near 35 mph, and he was moving north-northeast near the same speed! Danny’s center was located 540 miles south-southwest of Nantucket, Mass.; or 80 miles southeast of Cape Hatteras, North Carolina. He had an estimated minimum central pressure near 1007 millibars.

The Geostationary Operational Environmental Satellite, or GOES-12, operated by NOAA, caught a dying Danny on the U.S. east coast and an explosive Tropical Storm Jimena on the Mexican west coast this morning at 7:45 a.m. EDT. NASA’s GOES Project created imagery from the GOES-12 satellite that clearly shows Danny’s clouds stretched from the Mid-Atlantic north to New England. The image also shows a powerful Tropical Storm Jimena that developed early this morning.

Tropical Storm Jimena developed from one of the two areas that forecasters were watching yesterday. It developed and intensified quickly and by 8:18 a.m. this morning, Saturday, August 29, she had maximum sustained winds near 70 mph. Light upper level winds and warm sea surface temperatures are fueling her intensification.

At 9 a.m. EDT this morning, Jimena’s center was located about 270 miles southwest of Acapulco, Mexico near 14.2 north and 102.8 west. She was moving west near 10 mph and will turn north-northwest in the next day or so. Minimum central pressure is near 990 millibars. Jimena is expected to become a hurricane later today.
