Tropical Storm Chaba

Tropical Depression 16W in the Pacific Northwest grew into Tropical Storm Chaba over the past weekend, infrared imagery from NASA revealed powerful thunderstorms around Chaba's center.

Tropical Storm Chaba is now located about 525 nautical miles south-southeast of Kadena Air Base, Okinawa, Japan.

On October 25 at 1500 UTC (11 a.m. EDT) Chaba had maximum sustained winds near 60 knots (xx mph). It was still in open waters of the western North Pacific Ocean, near 18.3 North and 129.7 East. It was moving northwestward near 9 mph, and generating 19 foot-high seas.

NASA's Aqua satellite passed over Chaba on Sunday, Oct. 24 at 17:11 UTC (1:11 p.m. EDT) and captured an infrared image of the storm's cold cloud tops with th e Atmospheric Infrared Sounder (AIRS) instrument. At that time, Chaba's coldest cloud tops were as cold as or colder than -63 Fahrenheit indicating strong convection around the south and western edges of the center. The colder the thunderstrorm cloud tops, the higher the storms, and the stronger the thunderstorms.

Typhoon Megi Northwest Pacific Ocean

On October 18, 2010, Typhoon Megi approached and made landfall in the northeastern Isabela Province of the Philippines. Spanning more than 600 kilometers (370 miles) across, Megi was the 15th tropical storm and 7th typhoon of the season in the western Pacific Ocean. It was the most intense tropical cyclone of the year to date.

News reports indicated at least one death and an unknown number of injuries, as power and communications was cut off to more than 90 percent of Isabela and Cagayan provinces. In addition to the immediate damage, officials were concerned about the long-term damage to the rice crop, a staple of the national diet.

This image was taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite at 10:35 a.m. Philippine Time (02:35 UTC) on October 18, 2010. Megi was bearing down on Palanan Bay as a “super typhoon” with category 5 strength on the Saffir Simpson scale. As of 8:00 a.m. local time, the storm had sustained winds of 268 kilometers (167 miles) per hour, according to the Joint Typhoon Warning Center.

Hurricane Paula (Atlantic Ocean)

Paula as it traveled directly above on October 14, 2010 at 1437 UTC (10:47 AM EDT). The heaviest precipitation shown by TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data was off the coast of north-western Cuba. Paula was only producing scattered light to moderate rainfall elsewhere over western Cuba and the Florida Keys.

Hurricane Paula
was downgraded to a tropical storm at 1500 UTC (11:00 AM EDT) by the National Hurricane Center. Vertical wind shear, dry air entrainment and interaction with the mountainous terrain of western Cuban are predicted to continue to weaken Paula during the next twenty four hours. TRMM is a joint mission between NASA and the Japanese space agency JAXA.

Hurricane Otto

Otto had maximum sustained winds near 75 mph, and the National Hurricane Center in Miami, Fla. noted that some strengthening is possible before it weakens on Saturday, Oct. 9. Otto was located about 445 miles south of Bermuda near 25.9 North and 64.0 West. It was moving east-northeast near 17 mph, and had a minimum central pressure of 979 millibars.

On Oct. 7 at 1729 UTC (1:29 p.m. EDT) NASA's Aqua satellite passed over Otto and the Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of its cloud temperatures. The image showed that the highest, coldest thunderstorm cloud tops colder than -65 Fahrenheit were around Otto's center and throughout the large band of strong thunderstorms extending from the southeast of Otto's circulation. That band of strong thunderstorms brought heavy rainfall on the already soaked areas of the northern Leeward Islands, the Virgin Islands, and Puerto Rico.

Tropical Storm Otto Atlantic Ocean

At 11 a.m. EDT on Oct. 7, Tropical Storm Otto had maximum sustained winds near 60 mph, and strengthening is likely, according to the National Hurricane Center. Otto could become a hurricane in the next day or two. Otto was located about 255 miles northeast of Grand Turk Island or 620 miles south-southwest of Bermuda near 23.8 North latitude and 68.0 West longitude. Otto is far away enough from any land areas that there are no watches or warnings in effect. Otto was slowly trudging through the Atlantic Ocean at 2 mph and moving northeast. Otto's minimum central pressure was 992 millibars.

Tropical Depression 14W (Northwest Pacific Ocean)

At 5 a.m. EDT, October 5, Tropical Depression 14W had maximum sustained winds near 34 mph. It was located over Hainan Island near 19.5 North and 109.4 East. Its winds were creating 9-foot high seas. TD14W was moving north at 6 mph. It is expected to make a turn to the north-northeast, make a brief landfall in the mainland of southern China. Once there, it is forecast to move east, then east-southeast, making a half-circle and head toward the eastern end of Hainan Island and dissipate.

Tropical Moisture Bring Heavy Rain, Flooding To U.S. East Coast

The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center provides estimates of rainfall over the global Tropics. TMPA rainfall totals are shown here for the East Coast of the United States down to the northwest Caribbean for the period from September 24 to October 1, 2010.

The highest rainfall totals for the period are over Jamaica where upwards of 550 mm of rain fell (~22 inches) as a result of Nicole's interaction with the island's terrain. The highest totals along the East Coast occurred over coastal North Carolina where up to 500 mm of rain (~20 inches) fell. Almost all of eastern North Carolina received at least 200 to 250 mm of rain (~8 to 10 inches).

Numerous areas from northern Florida all the way up into central Pennsylvania received at least 100 mm (~4 inches) of rain with several areas in excess of 150 to 200 mm of rain (~6 to 8 inches). Locally, upwards of 9 inches of rain were reported around the Chesapeake Bay in Maryland and just over 20 inches in parts of North Carolina.

Although the rain ended a dry spell for the region, 4 deaths are being blamed on the storm in North Carolina. In Jamaica, 12 people are reported to have died as a result of Tropical Storm Nicole.
