DISCUSSION AND OUTLOOK
At 500 PM AST (2100 UTC), the center of Hurricane Sam was located near latitude 16.3 North, longitude 52.7 West. Sam is moving toward the northwest near 9 mph (15 km/h), and this motion is expected to continue for the next few days, with an increase in forward speed beginning on Thursday. A turn to the north is expected by Friday. On the forecast track, Sam will pass well to the northeast of the northern Leeward Islands Wednesday and Thursday.
An Air Force Reserve Hurricane Hunter aircraft indicates that the maximum sustained winds are near 120 mph (195 km/h) with higher gusts. Sam is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some strengthening is expected through tonight. Thereafter, fluctuations in intensity are possible through Thursday.
Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km).
The minimum central pressure measured by the aircraft is 957 mb (28.26 inches).
HAZARDS AFFECTING LAND
SURF: Swells generated by Sam will impact the Lesser Antilles for the next several days. Swells are expected to reach Bermuda and the Bahamas mid-to-late week, and then spread to the United States east coast late this week. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
