(CMR) Tropical Storm Nana is on a current path to impact both the coast of Belize and northern Honduras which includes Roatan and the Bay Islands. A Tropical Storm Watch has already been issued for those areas and the Caribbean Sea costs of Guatemala with expected tropical storm conditions starting late tomorrow.
The Cayman Islands National Weather Service has indicated that Tropical Storm Nana is forecast to pass 150 miles south of Grand Cayman tomorrow morning and is likely to become a hurricane as it heads towards Belize/Honduras for Thursday. We can expect an increase in cloudiness and showers as a result of the disturbance with upwards of 1 inch of rainfall and winds between 10 to 15 knots with higher gusts. The next bulletin will be issued in the morning at 7:00 a.m.
The 8:00 p.m. EDT advisory notes that the center of the Tropical Storm Nana was located over the central Caribbean Sea about 370 miles (600 km) east-northeast of Limon, Honduras, and about 535 miles (865 km) east of Belize City. Nana is moving toward the west near 18 mph (30 km/h), and this general motion is expected to continue through Thursday. On the forecast track, Nana will be moving near but north of the coast of Honduras on Wednesday and likely be approaching the coast of Belize Wednesday night and early Thursday.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center, mainly northeast through northwest of the center. Strengthening is forecast to occur during the next 48 hours, and Nana could become a hurricane just prior to landfall early Thursday.
A dangerous storm surge will raise water levels by as much as 3 to 5 feet above normal tide levels along the immediate coast near and to the north of where the center makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. Nana is expected to produce rainfall accumulations of 3 to 6 inches in Belize, and 2 to 4 inches across northern Honduras and the southeast portion of the Mexican state of Quintan Roo.
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 life-threatening surf and rip current conditions. Please consult products from your local weather office.
The next complete advisory will be issued by NHC at 11 p.m. EDT.
