A Tropical Storm Watch is in effect for...
- Northern Honduras
- Roatan Island and the Bay Islands of Honduras
- Belize

A Tropical Storm Watch may be required for portions of Guatemala and the southern Yucatan Peninsula later today.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.

For storm information specific to your area, please monitor products issued by your national meteorological service.

WIND: Tropical storm conditions are possible within the watch areas by late Wednesday.

RAINFALL: Nana is expected to produce rainfall accumulations of 2 to 4 inches across northern Honduras, Belize, and the southeast portion of the Mexican state of Quintana Roo.

SURF: Swells generated by this system are affecting portions of the southern coast of Jamaica, and will continue into Wednesday morning. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.
