DISCUSSION AND OUTLOOK
At 100 PM EST (1800 UTC), the center of Tropical Storm Eta was
located by satellites and NOAA Doppler weather radars near latitude
24.2 North, longitude 84.2 West. Eta is moving toward the southwest
near 16 mph (26 km/h), and this motion with some reduction in
forward speed is expected to continue through tonight. Little
overall motion is forecast on Tuesday and a slow northward motion is
expected on Wednesday. On the forecast track, the center of Eta
will continue to move away from the Florida Keys and south Florida
today, and will remain over the southeastern Gulf of Mexico tonight
Data from a recent Air Force Reserve reconnaissance mission and
Doppler radars indicate that maximum sustained winds have decreased
to near 50 mph (85 km/h) with higher gusts. Little change in
strength is expected today and tonight. Some slight strengthening is
forecast on Tuesday into Wednesday, followed by gradual weakening
Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.
The estimated minimum central pressure based on recent reports from
the aircraft is 995 mb (29.38 inches).
