The hurricane season in the eastern Pacific isn't over and Hurricane Kenneth serves as a reminder that the season ends November 30. NASA satellite imagery shows Kenneth more organized than it appeared on Sunday, Nov. 20 and became a late season hurricane.
Kenneth began as the thirteenth tropical depression and that formed on Saturday, November 19, about 480 miles south of Acapulco, Mexico. On Sunday, November 29 at 0300 UTC (11 p.m. EST, Nov. 19) the National Hurricane Center noted that the center of Tropical Depression 13E was further north than previously estimated and it had intensified into Tropical Storm Kenneth.
Kenneth is noteworthy because it is a named storm that is one of the latest forming in the Eastern Pacific Ocean in 28 years.
By 10 a.m. EST on Nov. 21, Kenneth strengthened into a hurricane. Kenneth's maximum sustained winds were near 80 mph (130 kmh) and further strengthening is expected. Kenneth was centered about 705 miles (1135 km) south of the southern tip of Baja California, near 12.7 North and 109.6 west.
It was moving to the west-northwest near 14 mph (22 kmh) and had a minimum central pressure of 989 millibars. Kenneth is forecast to turn to the west and slow down.
When the Tropical Rainfall Measuring Mission satellite called "TRMM" passed over Kenneth on Nov. 21 at 15:00 UTC (10:00 a.m. EST) the instruments aboard gathered data that provided a rainfall analysis.
The TRMM satellite is co-managed by NASA and JAXA, and the data was created into an image at NASA's Goddard Space Flight Center in Greenbelt, Md. The image showed a ragged eye was forming.
The data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) showed heavy rainfall was occurring around Kenneth's center.
Some of the heaviest rainfall was falling at a rate of over 2 inches (50 mm) per hour. The TRMM image also revealed a well-defined band of thunderstorms wrapping in the center of circulation as Kenneth continues to strengthen.
Wind shear is expected to be light in Kenneth's path, and although the waters will cool somewhat, Kenneth may still become a major hurricane.

GOES Satellite Eyeing Late Season Lows for Tropical Development
Greenbelt, MD (SPX) Nov 21, 2011
Its late in the Atlantic and eastern Pacific hurricane seasons, but the calendar isn't stopping the tropics. The GOES-13 satellite is keeping forecasters informed about developing lows like System 90E in the eastern Pacific and another low pressure area in the Atlantic. System 90E and the Atlantic low pressure area were both captured in one image from the NOAA's GOES-13 satellite, Nov. 18, ... read more
