Tropical cyclone Laurence made landfall early on December 21, and residents along the northern coast of Western Australia are experiencing strong gusty winds, flooding, and very heavy rainfall. Laurence made landfall near Wallal as a Category Three hurricane on the Saffir-Simpson Scale, with winds of 126 mph/ 203.7 kph/110 knots, gusting to 178 mph/287 kph/155 knots.

At 10 a.m. ET on December 15, Mick's sustained winds were around tropical depression force, 35 mph. It was located about 185 nautical miles east-southeast of Suva, Fiji, near 20.2 South and 177.4 West. Mick was moving east-southeast near 9 mph.
Strong vertical wind shear has helped expose Mick's low-level circulation center and the strong convection and thunderstorms are almost gone. As Mick continues to fade, its remnants will move southeastward. It is expected to dissipate by the end of the day.

Tropical Storm Laurence Set for 2nd Australian Landfall
Tropical Storm Laurence on Dec. 14 at 1343 UTC (8:43 a.m. ET), when it was west-northwest of Darwin, Australia. Satellite imagery showed a disorganized storm.
Tropical Storm Laurence tracked through Darwin Australia this weekend before sliding back into the Timor Sea and now Laurence is forecast to make a second landfall in Australia. Laurence is forecast to make landfall north of Wyndham then parallel the coastline while moving over land for the next couple of days.
Laurence is forecast to make landfall in the Kimberley region, move southwest through the northern area of the Great Sandy Desert and into the Pilbara region.
Tropical cyclones such as 05B in 3-D. An intense thunderstorm near the center of 05B is shown by TRMM's PR to extend to heights above 13 km (~8 miles)
Tropical Depression 05B is dissipating on the east coast of Sri Lanka today and over the next couple of days, but not before bringing some moderate and heavy rain over the next couple of days to some areas in Sri Lanka and the southeast coast of India, from Chennai, southward.

Rainfall in the once-known Cyclone Cleo has really diminished over the last 24 hours, and the Tropical Rainfall Measuring Mission or TRMM satellite has confirmed it. Cleo is fading and the Joint Typhoon Warning Center has acknowledged its demise, in its final warning on the storm today.
At 4 a.m. ET today, December 11, Cleo's maximum sustained winds were down to 40 mph, and waning fast. That make Cleo a weak tropical storm at the moment, but it is expected to dissipate in the next day or two, because of hostile atmospheric conditions (wind shear). Cleo's center was located about 480 miles southwest of Diego Garcia, near 13.9 degree South latitude and 67.7 East longitude.

Cleo has run into wind shear and it has weakened it from a cyclone to a tropical storm. Cleo's maximum sustained winds are now down to 69 mph, and expected to continue falling. NASA's TRMM satellite noticed that an opening in the storm's circulation is one of the reasons Cleo has weakened quickly.
On December 10 at 09:00 UTC (4 a.m. ET) Tropical Storm Cleo) was located approximately 380 nm south-southwest of the island of Diego Garcia, near 13.5 degrees South latitude and 70.3 East longitude. Cleo was moving west-southwestward at 7 mph.

On December 3 at 0300 UTC, the Joint Typhoon Warning Center issued its final advisory on Tropical Depression Nida. Nida had maximum sustained winds down to 28 mph (25 knots), and was still crawling along at 4 mph to the northwest. It was located about 450 miles southeast of Kadena, near 21.6 North latitude and 134.2 East longitude.

Moderate to strong winds blowing from the Northeast will prevail over Luzon and Visayas and coming from the North to Northwest over Eastern Mindanao and the coastal waters along these areas will be moderate to rough. Elsewhere, winds will be light to moderate blowing from the Northeast to Northwest with slight to moderate seas except duirng thunderstorms.

Nida is still holding on to Super Typhoon status in the Western Pacific Ocean, and over the weekend, is forecast to pass east of both Iwo To and Chichi Jima islands. Although the center of Nida will remain at sea, both islands will face heavy surf, gusty winds and heavy rainfall.
On Friday, November 27, at 0900 UTC (4 a.m. ET or 6 p.m. local Asia/Toyko time) Nida had maximum sustained winds near 149 mph (130 knots) with gusts to 184 mph (160 knots)! That makes Nida a Category 4 Typhoon. The range of sustained winds for a Category 4 typhoon (or hurricane) range from 131 to 155 mph (114-135 knots or 210-249 kilometers/hour).The National Hurricane Center says of a Category 4 Typhoon/hurricane: "Extremely dangerous winds causing devastating damage are expected."

Moderate to strong winds blowing from the Northeast will prevail over Luzon with moderate to rough seas. Elsewhere, light to moderate Northerly to Northwesterly winds will prevail and the coastal waters along these areas will be slight to moderate.

Residents in eastern Virginia and northeastern North Carolina were hit especially hard by the heavy rains from last week's coastal low pressure area, formerly known as hurricane Ida. Employees at NASA's Wallops Island facility in Wallops Island, Virginia had a first-hand experience with "Ida the coastal low."
After receiving almost a foot of water in various areas, clean up efforts will continue for some time to come. "The basement of my home did experience some flooding," Powell said. "Although frustrating, I know it can be cleaned up and repaired, however others weren't as lucky, so I won't complain."
NASA's QuikScat satellite uses microwave technology to peer through a tropical cyclone's clouds, and actually read the speed of the rotating surface winds. In an overpass from space at 7:58 p.m. ET last night, November 18 (Nov. 19 at 0058 UTC), QuikScat noticed Anja's maximum sustained winds have dropped to 63 mph, making it a tropical storm
