DISCUSSION AND OUTLOOK ---------------------- At 800 AM AST (1200 UTC), the center of Hurricane Lorenzo was located near latitude 29.4 North, longitude 42.9 West. Lorenzo is moving toward the north-northeast near 14 mph (20 km/h). A turn to the northeast is expected later today with a gradual increase in forward speed through Wednesday. On the forecast track, the center of Lorenzo is expected to pass near the western Azores early on Wednesday. Maximum sustained winds are near 105 mph (165 km/h) with higher gusts. Some weakening is forecast during the next 48 hours, but Lorenzo is forecast to remain a large and powerful hurricane while it passes near the Azores. Hurricane-force winds extend outward up to 90 miles (150 km) from the center and tropical-storm-force winds extend outward up to 255 miles (405 km). The estimated minimum central pressure is 957 mb (28.26 inches).

Tropical storm conditions are possible in the tropical storm watch area by early Wednesday. RAINFALL: Lorenzo is expected to produce total rain accumulations of 2 to 4 inches over much of the western Azores and around 1 inch over the central Azores Tuesday and Wednesday. This rainfall could cause life-threatening flash flooding in the western Azores. SURF: Swells generated by Lorenzo are spreading across much of the North Atlantic basin. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
