Tropical Storm Laura is the twelfth named storm of the 2008 Atlantic hurricane season, and the first subtropical cyclone. Laura formed out of a large non-tropical low pressure area located 1015 miles (1635 km) west of the western islands of the Azores on September 29.

Meteorological History

In late September, a large non-tropical system located over the north-central Atlantic slowly moved westward away from the Azores. The low produced hurricane-force winds, but did not exhibit the characteristics of a tropical cyclone. The storm steadily weakened over the following days, but developed tropical characteristics as it moved over slightly warmer waters. By September 29, the low had developed sufficient convection and was declared Subtropical Storm Laura. Upon being upgraded, cold cloud tops began to wrap around the center of Laura and consolidate near the center of circulation. The convection organized around the center quickly and a satellite pass over the storm revealed that it could be intensifying. A later satellite pass disregarded the possibility of intensification as the intensity was confirmed to be at 60 mph (95 km/h). The overall structure of Laura remained subtropical but there were indications that it might have been acquiring tropical characteristics.

Impact

Subtropical Storm Laura, as of September 29, is located over the open waters of the Central Atlantic and has not caused any impact on land.

Current storm information

As of 5 a.m. AST (0900 UTC) September 30, Subtropical Storm Laura is located within 20 nautical miles of 40.3°N 49.0°W, about 485 mi (785 km) south-southeast of Cape Race, Newfoundland. Maximum sustained winds are 50 knots (60 mph, 95 km/h), with stronger gusts. Minimum central pressure is 996 mbar (hPa; 29.41 InHg), and the system is moving north at 11 kt (13 mph, 20 km/h).

Tropical storm-force winds extend out up to 220 mi (350 km) from the center of Laura. It is currently not a threat to any land areas.
