Tropical Cyclone Haley about to dissipate in Southern Pacific Ocean

Tropical Cyclone Haley about to dissipate in Southern Pacific Ocean

Storm system 93P (known in Fiji as 14F) developed in South Pacific Ocean on February 9, 2013.  On February 10, 2013 the system developed into  Tropical Cyclone Haley, about 325 nautical miles (374 miles/602 km) south-southwest of Bora Bora, Society Islands, French Polynesia, in the open waters of the South Pacific Ocean. Maximum sustained winds strengthened quickly to 45 knots (51.7 mph/83.3 kph).

Soon after Haley intensified, infrared satellite imagery indicated that convection (rising air that forms thunderstorms that make up the storm) were already weakening around the center and on February 11, 2013 maximum sustained winds had already dropped to 35 knots (40.2 mph/64.8 kph).

The forecasters at the Joint Typhoon Warning Center expect Haley to continue moving southeast as wind shear increases and sea surface temperatures become even cooler. Both of those factors are expected to dissipate Haley by the end of February 12, 2013.
