Severe Cyclone Lam Reaches Hurricane Intensity Near Wessel Islands

Tropical Cyclone Lam reached hurricane intensity near the northern coast of Australia and was upgraded to Severe Cyclone status.  At 10:00 p.m. EST on Tuesday the center of Severe Cyclone Lam was located at latitude 11.1°S and longitude 137.0°E which put it near the Wessel Islands, about 80 miles north of Nhulunbuy and about 110 miles northeast of Elcho Island, Australia.  Lam was moving toward the west at 8 m.p.h.  The maximum sustained wind speed was 75 m.p.h. and there were gusts to 100 m.p.h.  The minimum surface pressure was 976 mb.

Lam remains over very warm Sea Surface Temperatures and the vertical wind shear is modest.  So, it has the potential to intensify further as long as the center remains over water.  A subtropical ridge is steering Lam westward and that motion is expect to continue for another 8 to 16 hours.  When it reaches the western edge of the ridge, Lam is expected to turn toward the southwest and it could make a landfall west of Elcho Island in 24 to 36 hours.  Lam is strong enough to pose a risk of a significant storm surge and it could also produce locally heavy rainfall and flooding as it moves inland.
