Mexico - November 20th, 2011

A small part of Tropical Storm Kenneth can be seen south of Mexico in the lower left corner of this image. According to forecasters, it is the latest-forming tropical cyclone in the North Pacific east of 140°W since Tropical Depression Twenty-Two-E on November 24, 1987, as well as the latest forming named storm since Winnie in 1983. Since 1949, only a total of three storms are known to have formed later than this, the others being Sharon in 1971 and an unnamed storm in 1951.

Early on November 16, an area of disturbed weather formed several hundred miles to the south of the southern coast of Guatemala. For the next 3 days, the disturbance moved towards the west, as it gradually organized, displaying intense thunderstorm activity at times. By November 19, the disturbance had gained enough organization to be declared as a tropical depression, the thirteenth of the season. The next day, the depression organized enough to become a tropical storm, and earned the name Kenneth.

As of 1 p.m. PST (2100 UTC) November 20, Tropical Storm Kenneth was located within 40 nautical miles of 11.5°N 105.6°W, about 525 mi (845 km) south of Manzanillo, Mexico. Maximum sustained winds are 35 knots (40 mph, 65 km/h), with stronger gusts. Minimum central pressure is 1005 mbar (hPa; 29.68 InHg), and the system is moving west-northwest at 11 kt (13 mph, 20 km/h). Tropical storm force winds extend outward up to 115 miles (185 km) from the center of Kenneth.
