For a complete depiction of forecast rainfall associated with Tropical Storm Rafael, please see the National Weather Service Storm Total Rainfall Graphic, available at www.nhc.noaa.gov/graphics_at3.shtml?rainqpf

STORM SURGE: Minor coastal flooding is possible in Jamaica tonight. Storm surge could raise water levels by 1-3 feet above normal tide levels in the Cayman Islands on Tuesday, and could raise water levels by as much as 6 to 9 feet above normal tide levels in areas of onshore winds along the southern coast of Pinar del Rio, Cuba, including the Isle of Youth.

The combination of a storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide…

Dry Tortugas…1-3 ft Lower Florida Keys…1-2 ft

SURF: Swells generated by the system are expected to affect much of the western Caribbean during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.
