Cyclone Becky Weakening Rapidly in the South Pacific
Hurricane Season 2007: Becky (Western Pacific)
Tropical cyclone Becky remains in the South Pacific Ocean near the island of New Caledonia and is expected to weaken into a remnant low pressure area by Fri., Mar. 30.
At 11:00 a.m. EDT (1500 UTC) on Thurs., Mar. 29, Becky was located near 21.5 degrees south latitude and 167.4 degrees east longitude, or about 75 miles northeast of Noumea, New Caledonia. Movement was toward the south-southwest at 4 knots (5 mph). Maximum sustained winds had decreased to near 25 knots (29 mph) with gusts to 35 knots (40 mph).
On Thurs., Mar. 29, satellite imagery showed a complete loss of thunderstorms, little deep, thick cloud cover, and a much less organized low level circulation. Forecasters expect Becky's remnants to drift slowly south-southwest as it dissipates.
This satellite image of Becky (above), taken at 7:30 a.m. EDT (1130 UTC) on Thurs., Mar. 29, shows a weak, ill-defined cyclone. Note the lack of deep, thick clouds (bright white) near the storm center (red marking), located to the northeast of New Caledonia. Image credit: JTWC/SATOPS.

New Cyclone Gaining Strength in the South Pacific Ocean
Tropical cyclone Becky developed in the South Pacific Ocean late Mon., Mar. 26, and is expected to steadily gain intensity as it approaches the island territory of New Caledonia by Thurs., Mar. 29.
At 11:00 a.m. EDT (1500 UTC) on Tues., Mar. 27, Becky was located near 16.4 degrees south latitude and 166.5 degrees east longitude, or about 155 miles northwest of Port Vila, Vanuatu. Movement was toward the east-southeast at 11 knots (13 mph). Maximum sustained winds were near 65 knots (75 mph) with gusts to 80 knots (92 mph).
Becky has intensified over the past 12 hours and recent satellite imagery shows that thunderstorms and deep, thick clouds are becoming more organized and consolidated around the storm center. The storm will continue on a southerly path, but its forward movement may slow after about 24 hours as it experiences greater wind shear (changing wind speed and direction with height). Overall, meteorologists expect conditions in the upper atmosphere to support further intensification through at least late Wed., Mar. 28.

This image of Tropical Cyclone Becky, taken by the Tropical Rainfall Measuring Mission (TRMM) satellite at 5:23 a.m. EDT (0923 UTC) on Tues., Mar. 27, shows a top-down-view of rain intensity. Estimated rain rates of 15 to 25 millimeters (0.59 inches to 0.98 inches) per hour were most common, with isolated areas of extreme rainfall (near 45 millimeters, or 1.77 inches per hour). TRMM is a joint mission between NASA and the Japanese space agency JAXA. Caption credit: Mike Bettwy, RSIS/Goddard Space Flight Center
