NASA sees Tropical Cyclone Garry continue to intensifyJanuary 24, 2013 in Earth / Earth Sciences
Tropical Cyclone Garry is in a good environment to intensify and satellite imagery from NOAA's GOES-15 satellite helped confirm that the storm has become more organized.
NOAA's GOES-15 satellite captured an infrared image of Tropical Storm Garry when it was located about 330 nautical miles (379.8 miles/ 611.2 km) east of Pago Pago, American Samoa. The image, created by the NASA GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md., was taken Jan. 24 at 1500 UTC (10 a.m. EST). The image showed a bright white circle of clouds that indicate strong thunderstorms were wrapping around the center of circulation as Garry continues to intensify. The latest bulletin from the Joint Typhoon Warning Center noted that microwave satellite imagery confirmed deep convection wrapping almost entirely around Garry's well-defined low level circulation center.
NOAA's GOES-15 satellite is in a fixed orbit over the Pacific Ocean, midway between Hawaii and the West Coast and 22,300 miles above the equator. GOES-15 provides a good view of what is happening in U.S. west and in the Pacific Ocean.
On Jan. 24 at 0900 UTC, Garry's maximum sustained winds had increased to 60 knots (69 mph/111.1 kph). Garry's tropical-storm-force winds extend about 55 nautical miles (63.3 miles/102 km) from the center, making it a compact tropical cyclone. It was centered near 14.0 south latitude and 164.9 west longitude and moving to the southeast at 11 knots (12.6 mph/20.3 kph).
Forecasters at JTWC expect that Garry will continue moving southeast and is expected to pass far south of French Polynesia. Garry is expected to briefly reach cyclone (hurricane) strength before wind shear weakens and dissipates the storm.
