Atlantic Storms: Tropical Depression Karen, Tropical Storm Jerry, Tropical Storm Lorenzo Path Map Updates

Three tropical cyclones are currently churning in the Atlantic Ocean, according to the National Hurricane Center (NHC.)

Tropical Depression Karen—which as of 2 a.m. EDT was located in the eastern Caribbean around 115 miles southwest of St. Croix, U.S. Virgin Islands—is moving northwards at approximately 8 miles per hour.

Karen is slowly strengthening and nearing tropical storm strength with maximum sustained wind speeds of 35 miles per hour and stronger gusts. Forecaster say that its center will pass near or over Puerto Rico and the Virgin Islands today, before moving across the western Atlantic later tonight and Wednesday.

Karen is expected to bring heavy rain and gusty winds to Puerto Rico and both the British and U.S. Virgin Islands as it passes, where tropical storm warnings are in effect.

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.

"Regardless of Karen's status and intensity, the system is expected to bring heavy rainfall, flash floods and mudslides to Puerto Rico and the U.S. Virgin Islands on Tuesday," an NHC statement read. "The rainfall and potential flooding will likely continue on Wednesday even as the center of Karen moves away from Puerto Rico and the Virgin Islands.

Karen is expected to bring between 2 and 4 inches of rain to Puerto Rico and the Virgin Islands, with isolated totals of 8 inches in some areas. This has the potential to cause flash flooding and mudslides, particularly in mountainous terrain.

At present it is too early to tell whether Karen will affect the mainland United States or the Bahamas because the forecast beyond later this week is highly uncertain, according to The Weather Channel.

Further to the north, Tropical Storm Jerry has begun weakening over the western Atlantic. The storm is located around 290 miles southwest of Bermuda with maximum sustained wind speeds of 60 miles per hour. Tropical-storm force winds extend outward up to 175 miles from the center.

It is moving northwards at around 7 miles per hour, and is expected to turn northeast today, and pass Bermuda by early Wednesday, where a Tropical Storm Warning is in effect.

"Tropical-storm-force winds are expected on Bermuda by late Tuesday," an NHC statement read. "Large swells are also expected to affect the coast of Bermuda during the next few days. These swells could cause life-threatening rip currents."

Finally, far out to the east, Tropical Storm Lorenzo is forecast to become a hurricane by Tuesday night over open waters.

Lorenzo is currently located around 270 miles southwest of the southernmost Cape Verde islands off the coast of Northwest Africa with maximum sustained wind speeds of 50 miles per hour.

With tropical-storm force winds extending outwards up to 90 miles from its center, Lorenzo is moving westwards at around 15 miles per hour—a motion that is expected to continue for the next few days. At present, the storm is not expected to affect any land areas.
