Subtropical Storm Laura is the twelfth named storm of the 2008 Atlantic hurricane season, and the first subtropical cyclone. Laura formed out of 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 upon being monitored for development but the winds weakened slightly over the following days. The low slowly developed tropical characteristics as it moved towards 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.

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 11 a.m. AST (1500 UTC) September 29, Subtropical Storm Laura is located within 20 nautical miles of 37.4°N 47.8°W, about 695 mi (1120 km) south-southeast of Cape Race, Newfoundland and Labrador. Maximum sustained winds are 50 knots (60 mph, 95 km/h), with stronger gusts. Minimum central pressure is 995 mbar (hPa; 29.38 InHg), and the system is moving west-northwest at 7 kt (8 mph, 13 km/h).

Laura is a large system with tropical storm force winds extending up to 275 mi (445 km) from the center. It is currently not a threat to any land areas.
