DISCUSSION AND OUTLOOK
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Delta was
located near latitude 16.4 North, longitude 78.6 West. Delta is
moving toward the west near 7 mph (11 km/h), and a turn toward the
west-northwest is forecast later today. A faster northwestward
motion is expected on Tuesday and Wednesday. On the forecast
track, the center of Delta is expected to move away from Jamaica
later today, move near or over the Cayman Islands early Tuesday,
and approach western Cuba Tuesday afternoon or evening. Delta is
forecast to move into the southeastern Gulf of Mexico Tuesday
night, and be over the south-central Gulf of Mexico on Wednesday.
Maximum sustained winds have increased to near 45 mph (75 km/h)
with higher gusts. Additional strengthening is expected during the
next few days, and Delta is expected to become a hurricane on
Tuesday before it nears western Cuba.
Tropical-storm-force winds extend outward up to 45 miles (75 km)
from the center.
The estimated minimum central pressure is 1002 mb (29.59 inches).
