DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Tropical Storm Chris was located near latitude 42.1 North, longitude 60.1 West. Chris is moving toward the northeast near 35 mph (56 km/h), and this general motion is expected to continue during the next 2 to 3 days. On the forecast track, the center of Chris will pass over or near extreme southeastern Newfoundland later today or tonight. Maximum sustained winds have decreased to near 70 mph (110 km/h) with higher gusts. Additional weakening is anticipated during the next few days, and Chris is expected to become a post-tropical cyclone later today. Tropical-storm-force winds extend outward up to 175 miles (280 km) from the center. The estimated minimum central pressure is 985 mb (29.09 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Even though Chris is moving away from the United States, swells generated by the storm will affect portions of the coast from North Carolina northward to New England during the next couple of days. Swells will spread northward along the southern coasts of Nova Scotia and Newfoundland overnight and into Thursday. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. RAINFALL: Chris is expected to produce total rain accumulations of 1 to 3 inches (25 to 75 millimeters) over Newfoundland, with possible isolated maximum amounts of 6 inches (150 millimeters). These rains may cause flash flooding. NEXT ADVISORY ------------- Next complete advisory at 1100 AM AST. $$ Forecaster Avila
