DISCUSSION AND OUTLOOK
At 500 PM EDT (2100 UTC), the center of Tropical Storm Zeta was
located near latitude 17.7 North, longitude 83.4 West. Zeta has
been 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.
Reports from a NOAA Hurricane Hunter aircraft indicate that
the maximum sustained winds have increased near 50 mph (85 km/h)
with higher gusts. Strengthening is forecast during the next 48
hours, and Zeta is expected to become a hurricane before it moves
near or over the Yucatan Peninsula late Monday.
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.
The minimum central pressure estimated from NOAA Hurricane Hunter
aircraft observations is 999 mb (29.50 inches).
