Hurricane Rina Update 10/25/11


Hurricane Rina, the 17th named system and the 5th hurricane of the 2011 Atlantic Hurricane Season is churning over the warm waters of the western Caribbean Sea. Rina is on the precipice of category 2-3 intensity on the Saffir-simpson hurricane scale with a minimum central pressure of 970 millibars and maximum sustained wind speeds of 110 miles per hour as of the 7pm advisory on October 25th from the National Hurricane Center. The forecast is for a strengthening system as it crawls north westward towards Mexico's Yucatan Peninsula. Hurricane Rina is expected to have a direct impact on the Yucatan on Thursday October 27th. There after, Rina is expected to move into the Gulf of Mexico where it will pose a threat to central and southern Florida. There are uncertainties on the track of Rina as it could plow into south Florida or loop south towards Cuba. Either way, Hurricane Rina is expected to move into an unfavorable region in the Gulf of Mexico where it will encounter strong wind shear aloft, this will prevent Rina form maintaining strength and even weaken the system all together from a hurricane down to a tropical storm.
