Tropical Storm Imani Southern Indian Ocean

On March 26, NASA’s Aqua satellite captured a visible image of Imani at 0836 UTC and showed that the northern half of the tropical cyclone contained very scattered thunderstorms which is conducive to strong wind shear in that quadrant of the storm.

Imani was still hanging onto tropical storm status on March 26 at 0900 UTC (5 a.m. EDT) with maximum sustained winds near 52 mph (45 knots), but the storm is running into vertical wind shear – basically a tropical cyclone killer. Imani was located about 810 nautical miles southwest of the Cocos Islands, near 21.3 South and 86.4 East. It was slugging southward at 3 mph (2 knots).

Tropical Storm Omais is fading fast in the northwestern Pacific Ocean

Tropical Storm Omais is fading fast in the northwestern Pacific Ocean, and will dissipate over the weekend according to the Joint Typhoon Warning Center. When NASA’s Aqua satellite flew over Omais late on March 25, it already showed signs of falling apart.

At 0900 UTC (5 a.m. EDT)on Friday, March 26, Tropical Storm Omais was barely hanging onto tropical storm strength with maximum sustained winds near 39 mph. It was located about 655 nautical miles southwest of the island of Iwo To (formerly Iwo Jima) near 18.3 North and 132.1 East. It was moving north-northeastward at 12 mph (11 knots) and quickly losing its tropical characteristics.

Tropical Storm Omais Weakens and Doubles in Size

Tropical storm Omais has run into wind shear in the northwestern Pacific Ocean, but as it has weakened overnight it has also doubled in size. NASA's Aqua satellite has captured both infrared and visible images early this morning of the larger Omais.

Late yesterday, March 24, Omais strengthened to (63 mph) 55 knots and now that it has run into an environment with stronger wind shear, it has already weakened. The wind shear has increased because of the approach of a frontal system which is currently about 215 nautical miles northwest of the storm.

Tropical Storm Imani in the Southern Indian Ocean

Tropical Storm Imani Making a Question Mark in the Southern Indian Ocean

Over the last week, the path that Tropical Storm Imani, formerly tropical cyclone 21S, is making in the Southern Indian Ocean resembles a question mark. However, there is no question in the minds of forecasters that Imani is headed south to finish out the "question mark" shape.At 0900 UTC (5 a.m. EDT) today, March 24, Tropical Storm Imani had maximum sustained winds near 63 mph (55 knots). Tropical storm-force winds extended out up to 55 miles from the center, making the storm about 110 miles in diameter. It was located about 745 miles west-southwest of Cocos Island, near 15.7 south and 86.3 East. It was moving southwest near 13 mph (11 knots).

Tropical Storm 21S

At 900 UTC (5 a.m. EDT) today, March 23, Tropical Cyclone 21S was located about 505 miles west of Cocos Island near 12.9 degrees South latitude and 88.3 degrees East longitude.

Tropical Storm 21S has maximum sustained winds near 46 mph (40 knots) and tropical storm-force winds extend out to about 45 miles from the center. Today’s NASA Aqua satellite visible image confirmed that 21S is a compact storm, about 90 miles in diameter.

Tropical Depression 02W Forms in Northwestern Pacific

When NASA's Aqua satellite flew over TD 02W this morning, Monday, March 22 at 0405 UTC (12:05 a.m. EDT), infrared imagery showed a large area of strong convection in the storm's center, where thunderstorm cloud tops were highest. Those cloud top temperatures were colder than -63 degrees Fahrenheit, indicating strong thunderstorms with moderate to heavy rainfall.

By 11 a.m. EDT (1500 UTC or 1 a.m. local time) today, TD 02W had maximum sustained winds near 35 mph (30 knots) and was near 8.4 degrees North latitude and 141.4 degrees East longitude. TD 02W is about 100 miles southeast of Fais, 150 miles east-southeast of Ulithi and 235 miles east-southeast of Yap. It was moving northwest near 10 mph (9 knots), and generating 10-foot high waves.

Queensland, Australia Now Expecting a Landfall from Cyclone Ului

Northeastern Queensland, Australia is on alert as Tropical Cyclone Ului continues tracking through the Coral Sea today, and is forecast to make a landfall on March 20. NASA's Terra and Aqua satellites have been providing satellite data on the storm to assist forecasters.

The Australian Bureau of Meteorology has issued a Tropical Cyclone Watch from Cardwell to Yeppoon in Queensland. There is also a High seas weather warning in effect for "metarea 10." Ocean vessels can expect very high seas and have been asked to report conditions to the Bureau. Meanwhile the Solomon Islands have also posted a Tropical Cyclone Watch for Rennell/Bellona.

On Thursday, March 18 at 1500 UTC (11 a.m. EDT), Tropical Cyclone Ului had maximum sustained winds near 92 mph (80 knots). The storm is about 300 miles in diameter. Tropical storm force winds extend about 155 miles from Ului's center, while hurricane force winds extend 45 miles out from the center. Ului was located about 670 nautical miles east of Cairns, Australia near near 15.9 South and 157.4 East. It has been crawling at 3 mph (2 knots) in a southwestward direction.
