DISCUSSION AND 48-HOUR OUTLOOK
At 400 AM CDT (0900 UTC), the center of Tropical Storm Nate was
located near latitude 16.9 North, longitude 85.1 West. Nate is
moving toward the north-northwest near 14 mph (22 km/h), and this
general track with a marked increase in forward speed is expected
during the next day or two. On the forecast track, the center of
Nate will move across the northwestern Caribbean Sea today, and
reach the eastern coast of the Yucatan peninsula early this evening.
Nate will then move into the southern Gulf of Mexico tonight and
approach the northern Gulf coast Saturday evening.
Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Strengthening is forecast during the next couple of days, and Nate
is expected to become a hurricane by the time it reaches the
northern Gulf of Mexico.
Tropical-storm-force winds extend outward up to 90 miles (150 km)
mainly to the east of the center.
The estimated minimum central pressure is 999 mb (29.50 inches).

U.S. Central Gulf Coast states: 3 to 6 inches, max 12 inches
Heavy rainfall will occur over a wide area, including locations well

areas of onshore winds on the Yucatan Peninsula and the adjacent
islands. Near the coast, the surge will be accompanied by large and
