Track of TS 11L

At 5:00 PM AST (21:00 UTC) the center of post-tropical cyclone Igor (11L) was located near latitude 49.3 north, longitude 51.7 west. The main image shows some convection on the western side of the storm over Canada.

Igor is moving toward the north-northeast near 39 mph (63 km/hr). A turn toward the north with a decrease in forward speed is expected by Wednesday, followed by a turn toward the northwest by Thursday.

Maximum sustained winds are near 80 mph (130 km/hr) with higher gusts. Little change in strength is expected during the next 24 hours, but the cyclone should begin to gradually weaken by late Wednesday.

Hurricane force winds extend outward up to 85 miles (140 km) from the center, and tropical storm force winds extend outward up to 520 miles (835 km). Estimated minimum central pressure is 950 mb (28.05 inches).

Hurricane Igor resulted in minor damage throughout Bermuda and significant damage in Newfoundland. Current hazards affecting land include wind, rainfall and high surf. Winds of tropical storm force and very near hurricane force, especially in gusts, are occurring in parts of Newfoundland. These winds will likely diminish Tuesday night as Igor moves farther to the north.

The significant rainfall threat over Newfoundland associated with Igor has come to an end. Rainfall will be tapering off this evening as the system moves rapidly north-northeastward.

Large swells along the east coast of the United States will be subsiding tonight. Swells will be slow to subside in Nova Scotia, Newfoundland, Puerto Rico, the Virgin Islands, Hispaniola and portions of the Bahamas during the next couple of days. These swells are likely to cause life-threatening surf and rip currents.

Track of TS 11L

As of 11 p.m. AST September 19 (0300 UTC September 20), Hurricane Igor (11L) is located within 30 nautical miles of 32.4°N 65.5°W, about 40 mi (65 km) west of Bermuda. It is currently affecting Bermuda and should continue to do so through Monday.

Maximum sustained winds are 65 knots (75 mph, 120 km/h), with stronger gusts. Minimum central pressure is 955 mbar (hPa; 28.20 InHg), and the system is moving north-northeast at 12 kt (14 mph, 22 km/h).

Igor is an extremely large hurricane and the largest Atlantic hurricane ever recorded in terms of tropical storm-force wind field; hurricane force winds extend up to 90 miles (150 km) from the center of Igor, and tropical storm force winds up to 345 miles (555 km) from the center. In the full image, the convection associated with the huge system appears to stretch from near Newfoundland to near Puerto Rico.

As of 2 p.m. AST (1800 UTC) September 19, Hurricane Igor (11L) is located within 30 nautical miles of 30.8°N 65.7°W, about 115 mi (185 km) south-southwest of Bermuda.

Maximum sustained winds are 75 knots (85 mph, 140 km/h), with stronger gusts. Minimum central pressure is 952 mbar (hPa; 28.11 InHg), and the system is moving at 14 kt (16 mph, 26 km/h).

Hurricane Igor is already affecting Bermuda. The outer rain bands will start to increase in frequency and intensity tonight, as conditions deteriorate and tropical storm force winds develop near the island.

Igor is an extremely large hurricane and the largest Atlantic hurricane ever recorded; hurricane force winds extend up to 90 miles (150 km) from the center of Igor, and tropical storm force winds up to 345 miles (555 km) from the center.

The complete extent of the hurricane is best appreciated by opening the full image, where the convection associated with the system can be seen stretching from north of Hispaniola to the latitude of Massachusetts, USA.

As of 11 p.m. AST September 17 (0300 UTC September 18), Hurricane Igor (11L) is located within 15 nautical miles of 24.6°N 62.0°W, about 560 miles (900 km) south-southeast of Bermuda.

Maximum sustained winds are 95 knots (110 mph, 175 km/h), with stronger gusts. Minimum central pressure is 947 mbar (hPa; 27.96 InHg), and the system is moving northwest at 11 kt (13 mph, 20 km/h).

Igor is an extremely large hurricane and one of the largest Atlantic hurricanes ever recorded; hurricane force winds extend up to 105 miles (165 km) from the center of Igor, and tropical storm force winds up to 345 miles (555 km) from the center.

The wind field is now sizably larger than even two very well-known devastating hurricanes that were also very large; Hurricane Ike in the 2008 season and Hurricane Katrina in the record-breaking 2005 season.
