As of 10 p.m. CDT (0300 UTC) October 27, Hurricane Rina was the eighteenth tropical cyclone, seventeenth named storm, and sixth hurricane of the 2011 Atlantic hurricane season.

Rina developed from a low-pressure area in the western Caribbean Sea on October 23. The depression quickly intensified, and was upgraded to Tropical Storm Rina early on the following day. Rina continued to rapidly strengthen as it tracked west-northwestward, and became a hurricane on October 24.

Rina eventually peaked as a high-end Category 2 hurricane while it moved generally westward on October 25. However, on October 26, Rina weakened substantially, and was downgraded to a Category 1 hurricane.

Further weakening occurred, and Rina was downgraded to a tropical storm on October 27. After being downgraded to a tropical storm, Rina continued to slowly weaken. Here, the storm is shown on October 28 at low strength.

At 7:00 AM CDT (1200 UTC) the center of Hurricane Rina was located near latitude 18.9 north, longitude 87.0 west. Rina is moving toward the northwest near 6 mph (9 km/h).

A gradual turn to the north with a slight increase in forward speed is expected today. On the forecast track, the center of Rina will be moving near or over the east coast of the Yucatan Peninsula tonight and Friday.

Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Rina is a category one hurricane on the Saffir-Simpson hurricane wind scale. Weakening is forecast during the next 48 hours, and Rina could become a tropical storm later today.

Hurricane force winds extend outward up to 15 miles (30 km) from the center, and tropical storm force winds extend outward up to 85 miles (140 km). The estimated minimum central pressure is 988 mb (29.18 inches).

Hazards affecting land include wind, rainfall and storm surge. Tropical storm conditions are likely occurring over portions of the tropical storm warning area. Hurricane conditions
are expected within the hurricane warning area later today.

Rina is expected to produce rainfall amounts of 3 to 6 inches over the eastern Yucatan Peninsula and Cozumel through Friday with isolated maximum amounts to 10 inches. A dangerous storm surge will raise water levels by as much as 2 to 4 feet above normal tide levels along the immediate coast near and to the right of the track of the center. Near the coast, the surge will be accompanied by large and destructive waves.
