DISCUSSION AND 48-HOUR OUTLOOK
At 1000 AM CDT (1500 UTC), the center of Tropical Storm Nate was
located near latitude 18.7 North, longitude 85.0 West. Nate is
moving toward the north-northwest near 21 mph (33 km/h) and this
motion is expected to continue through Saturday, with a turn toward
the north and northeast expected Saturday night and Sunday. On the
forecast track, the center of Nate will move across the
northwestern Caribbean Sea today, and move near or over the
northeastern coast of the Yucatan peninsula this evening. Nate will
then move into the southern Gulf of Mexico tonight, approach the
northern Gulf coast Saturday, and then move near or over the
northern Gulf coast Saturday night or Sunday.
Reports from Air Force Reserve and NOAA Hurricane Hunter aircraft
indicate that maximum sustained winds are now near 50 mph (85 km/h)
with higher gusts. Additional 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 115 miles (185 km)
mainly to the east of the center.
The minimum central pressure estimated from the Hurricane Hunter
data is 996 mb (29.42 inches).
