NASA's Aqua satellite sees birth of two tropical cyclones in Eastern Pacific

Summary:
The tropics in the eastern Pacific were quiet for a couple of days after Hurricane Hilary dissipated, and today gave birth to Tropical Depression 10 and Tropical Storm Irwin. NASA's Aqua satellite captured an infrared image of both storms and saw the powerful convection in the center of Irwin that enabled the storm to go from a depression to a tropical storm in a short time.

The tropics in the eastern Pacific were quiet for a couple of days after Hurricane Hilary dissipated, and today gave birth to Tropical Depression 10 and Tropical Storm Irwin. NASA's Aqua satellite captured an infrared image of both storms and saw the powerful convection in the center of Irwin that enabled the storm to go from a depression to a tropical storm in a short time.

The eleventh tropical depression quickly grew into Tropical Storm Irwin this morning, as strong convection surged around its center of circulation. That convection (rising air that creates the thunderstorms that power a tropical cyclone) was seen in infrared imagery taken early this morning, Oct. 6, from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite. The cold cloud tops from those strong thunderstorms were colder than -63 Fahrenheit (-52 Celsius) and represented the strength in the core of Irwin.

At 11 a.m. today, Oct. 6, Tropical Storm Irwin's maximum sustained winds had grown to 40 mph, after forming as a depression just 5 hours before. Irwin was located about 855 miles (1,375 km) south-southwest of the southern tip of Baja California, Mexico near 12.4 North and 116.8 West. It was moving away from land to the west-northwest near 6 mph (9 kmh). The National Hurricane Center expects Irwin to turn to the north and then north-northeast tomorrow. Irwin is expected to strengthen slowly in the next 48 hours. Minimum central pressure was 1005 millibars.

Closer to land, NASA's Aqua satellite saw a smaller Tropical Depression 10E. Tropical Depression 10E (TD10E) appears pretty close to Tropical Storm Irwin on the AIRS infrared imagery. It is located to the east-southeast of Tropical Storm Irwin, and it appears to be a smaller, more compact, rounded area of strong convection. Specifically, TD10E is located near 10.3 North and 105.8 West, about 610 miles south of Manzanillo, Mexico. It has maximum sustained winds near 35 mph (55 kmh) and is moving to the west-northwest near 8 mph (13 kmh). The AIRS infrared data shows strong convection around the southwestern edge of the center of circulation, indicating that TD10E could also become a tropical storm shortly.

The National Hurricane Center noted that "The tropical cyclone is forecast to remain over warm waters and in a low (wind) shear environment during the next several days" and predicts it could become a hurricane in two or three days. By mid-day on Saturday, Oct. 8, the National Hurricane Center forecast projects TD10E to change course and "recurve ahead of a large trough (elongated area of low pressure) diving southeastward across the southwest United States and the Baja Peninsula."
