DISCUSSION AND OUTLOOK
At 200 PM EDT (1800 UTC), the center of Hurricane Delta was located near latitude 18.5 North, longitude 83.5 West. Delta is moving toward the west-northwest near 16 mph (26 km/h). A west- northwestward to northwestward motion is expected over the next couple of days. A slower northwestward to north-northwest motion is forecast to begin by late Wednesday or Wednesday night.
On the forecast track, the center of Delta is expected to continue to pass southwest of the Cayman Islands through early this afternoon, and move over the northeastern portion of the Yucatan peninsula late tonight or early Wednesday. Delta is forecast to move over the southern Gulf of Mexico Wednesday afternoon, and be over the southern or central Gulf of Mexico through Thursday. Reports from a NOAA Hurricane Hunter aircraft indicate that the maximum sustained winds have increased to near 140 mph (220 km/h) with higher gusts.
Delta is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some additional strengthening is possible during the next 24 hours, and Delta is forecast to be an extremely dangerous category 4 hurricane when it reaches the Yucatan peninsula Wednesday. Although some weakening is likely when Delta moves over the Yucatan peninsula, re-strengthening is forecast when the hurricane moves over the southern Gulf of Mexico. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). The estimated minimum central pressure from NOAA reconnaissance aircraft data is 956 mb (28.23 inches).
