DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of Tropical Storm Zeta was
located near latitude 18.0 North, longitude 84.0 West.  Zeta is
meandering or nearly stationary, but a generally northwestward
motion is expected over the next couple of days.  On the forecast
track, the center of Zeta will pass south of western Cuba early
Monday and move near or over the northern Yucatan Peninsula or the
Yucatan Channel late Monday, move into the southern Gulf of Mexico
on Tuesday, and reach the central Gulf of Mexico by late Tuesday.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts.  Strengthening is forecast during the next 48 hours, and Zeta
could become a hurricane by the time it moves near or over the
Yucatan Peninsula late Monday.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).

By Wednesday, heavy rainfall associated with Zeta will begin to

conditions are expected within the warning area in the Yucatan
peninsula late Monday, and could occur in the warning area in
Western Cuba on Monday.
