DISCUSSION AND 48-HOUR OUTLOOK
At 400 AM CDT (0900 UTC), the center of Tropical Storm Franklin
was located by the Belize Weather Service Doppler radar to be near
latitude 19.3 North, longitude 88.5 West. Franklin is moving toward
the west-northwest near 14 mph (22 km/h). A west-northwestward to
westward motion is expected during the next couple of days. On the
forecast track, the center of Franklin will continue to move across
the Yucatan peninsula through today, and emerge over the Bay of
Campeche tonight. Franklin will then move westward across the Bay of
Campeche on Wednesday.
Maximum sustained winds have decreased to near 50 mph (85 km/h) with
higher gusts. Weakening is expected while Franklin moves across the
Yucatan peninsula today. Restrengthening is forecast to begin
tonight and Wednesday while Franklin moves over the Bay of Campeche.
Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center. Wind gusts to 47 mph (76 km/h) in squalls have been
measured during the past couple of hours by NOAA Buoy 42056,
located more than 200 miles east-northeast of Franklin's center.
The estimated minimum central pressure is 998 mb (29.47 inches).
HAZARDS AFFECTING LAND
RAINFALL: Rainfall amounts of 3 to 6 inches, with isolated amounts
of around 12 inches, are possible across the Yucatan Peninsula of
Mexico and Belize through Wednesday, with the highest amounts over
the Mexican state of Quintana Roo. In addition, Franklin is
expected to bring 4 to 8 inches of rainfall with isolated amounts
up to 15 inches through Thursday to northern Veracruz, Puebla,
Tlaxcala, Hidalgo, and eastern San Louis Potosi in eastern Mexico.
These rains will be capable of producing life-threatening flash
floods and mudslides.
WIND: Tropical storm conditions are likely still occurring over
portions of the east coast of the Yucatan peninsula. These
conditions should spread westward across the remainder of the
warning area today and diminish along the east coast of the Yucatan
peninsula later this morning. Hurricane or tropical storm conditions
are possible within the hurricane watch area by late Wednesday.
Tropical storm conditions are possible within the tropical storm
watch area tonight and Wednesday.
STORM SURGE: A storm surge will raise water levels by as much
as 1 foot above normal tide levels along the east coast of the
Yucatan peninsula early this morning. The surge will be
accompanied by large and destructive waves. Water levels are
expected to diminish after sunrise.
