DISCUSSION AND 48-HOUR OUTLOOK
At 700 AM CDT (1200 UTC), the center of Tropical Storm Colin was
located near latitude 26.4 North, longitude 87.3 West. Colin is
moving toward the north-northeast near 14 mph (22 km/h). A turn
toward the northeast with an increase in forward speed is expected
today. A rapid northeastward motion is expected tonight and
Tuesday. On this track, the center of Colin is forecast to approach
the coast of the Florida Big Bend area this afternoon or evening,
move across portions of Florida and southeastern Georgia early
Tuesday morning, and move near the southeastern coast of the United
States later on Tuesday.
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Little change in strength is forecast today before Colin
reaches the coast of Florida. Some slight strengthening is possible
on Tuesday when Colin is near the southeastern United States coast.
Tropical-storm-force winds extend outward up to 185 miles (295 km)
to the east of the center.
The estimated minimum central pressure is 1004 mb (29.65 inches).
HAZARDS AFFECTING LAND
RAINFALL...Colin is expected to produce rainfall amounts of 3 to 5
inches with isolated maximum totals of 8 inches possible across the
northeastern Yucatan peninsula, western Cuba, western to northern
Florida, southeastern Georgia, and coastal areas of the Carolinas
STORM SURGE...The combination of a storm surge and the tide will
cause normally dry areas near the coast to be flooded by rising
waters. The water could reach the following heights above ground if
the peak surge occurs at the time of high tide...
Indian Pass to Tampa Bay...1 to 3 ft with slightly higher amounts
possible in a few locations.
Tampa Bay south to Florida Bay...1 to 2 ft.
Localized coastal flooding and dangerous surf is possible along the
Florida east and Georgia coasts within the Tropical Storm Warning
area, as well as in the Tropical Storm Watch area along the Georgia
and South Carolina coasts.
The deepest water will occur along the immediate coast.
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.
WIND...Tropical storm conditions are expected to first reach the
Gulf coast within the warning area this afternoon, and the Atlantic
coast within the warning area by early Tuesday. Tropical storm
conditions are possible along the Atlantic coast within the watch
area on Tuesday.
TORNADOES...A few tornadoes are possible today and tonight across
portions of Florida and far southern Georgia.
