This infrared image of the eastern half of Tropical Storm Rina was taken on Oct. 24 at 2:47 a.m. EDT from the AIRS instrument on NASA's Aqua satellite. It shows a very large area of strong convection and thunderstorms around the center (purple) of circulation. Cloud top temperatures were colder than -63F (-52C) in that area, indicating strong thunderstorms and heavy rainfall.

Less than a day after Tropical Storm Rina formed, it has strengthened into a hurricane, the sixth of the 2011 Atlantic hurricane season.

Rina formed over the northwest Caribbean Sea, and is currently about 190 miles (305 kilometers) southwest of Grand Cayman and 370 miles (595 kilometers) of Chetumal, Mexico. The storm has winds of 75 mph (120 kph) is heading toward Belize and the Yucatan Peninsula of Mexico.

Rina is the 17th named storm of the 2011 season (storms receive names when they reach tropical storm or hurricane status).

The 2011 season was predicted to be a doozy, with 14 to 19 named storms (which include tropical storms and hurricanes), seven to 10 hurricanes and three to five major hurricanes (Category 3 or higher).

The most recent storm before Rina was Phillipe (the letter Q is skipped in the hurricane name list), which first formed in September and churned across the Atlantic for two weeks before becoming a hurricane on Oct. 6. It weakened shortly thereafter and the waters of the Atlantic, Gulf of Mexico and Caribbean were relatively quiet for most of October.

There is about one month left in the traditional Atlantic hurricane season, which begins each year on June 1 and ends on Nov. 30.
