On Sunday Earl intensified and became the third hurricane of the 2010 season in the Atlantic basin.
As of 5 p.m. ET, Hurricane Earl was centered 385 km (240 miles) east of Bermuda with maximum sustained winds of 140 kph (85 mph). A hurricane warning in is effect for the northern Leeward Islands and the British Virgin Islands and a hurricane watch is in place for Puerto Rico and the U.S. Virgin Islands.
In addition to strong winds, all of these areas will likely see 75-150 mm (3-6 inches) of rain, with higher elevations possibly receiving up to 300 mm (12 inches). That much rain has the potential to cause life-threatening flash floods and mudslides.
Also in the Atlantic basin, Hurricane Danielle moved harmlessly past Bermuda late Saturday. Danielle will continue to weaken and poses no threat to any landmass. To the east of Hurricane Earl, a strong tropical wave is threatening to become the sixth named storm of the season. The National Hurricane Center is giving the wave an 80 percent chance of developing over the next 48 hours.
In the western Pacific, the tropics are beginning to heat up as well. Tropical Storm Lionrock is nearly stationary about 300 km (185 miles) east-southeast of Hong Kong. Lionrock is not expected to intensify much but will bring heavy rain as it moves closer to the southern China coast early this week.
On the other hand, Tropical Storm Kompasu, which formed late Saturday, is growing steadily stronger and will likely become a typhoon on Monday. The current forecast from the Joint Typhoon Warning Center has Kompasu moving through the East China Sea and towards the western side of the Korean Peninsula by Thursday.
A low pressure system moving across Germany will continue to drop to the south on Monday. Accompanying this system will be the threat of severe thunderstorms that will include strong winds, large hail, and heavy rain. On Tuesday the threat of severe storms will move into eastern Europe.
