DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Delta was
located near latitude 16.2 North, longitude 79.4 West. Delta is
moving toward the west near 8 mph (13 km/h), and a turn toward the
west-northwest should occur this evening. A faster northwestward
motion is expected Tuesday through Wednesday night. On the
forecast track, the center of Delta is expected to pass southwest
of the Cayman Islands early Tuesday, and approach the northeastern
portion of the Yucatan peninsula and the Yucatan Channel Tuesday
afternoon or evening. Delta is forecast to move into the
southern Gulf of Mexico Tuesday night or early Wednesday, and be
over the south-central Gulf of Mexico on Wednesday and Wednesday
night.
Data from a NOAA Hurricane Hunter aircraft indicate that the
maximum sustained winds have rapidly increased to near 70 mph (110
km/h) with higher gusts. Additional rapid strengthening is
expected during the next day or so, and Delta is expected
to be a major hurricane when it nears the Yucatan Peninsula.
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
The minimum central pressure estimated from NOAA reconnaissance
aircraft data is 983 mb (29.03 inches).
