HOLT, Fla., Sept. 23, 2019—Tropical Depression Thirteen formed in the Atlantic late last night.

Tropical Depression 13

The depression is moving near 15 mph toward the west-northwest.

Maximum sustained winds are near 35 mph with higher gusts.

The National Hurricane Center is forecasting TD13 to strengthen during the next 48 hours.

The depression is expected to become Tropical Storm Lorenzo later today and Hurricane Lorenzo by tomorrow night or Wednesday.

Lorenzo is expected to be near major hurricane strength (111 mph) by Thursday, according to the NHC.

Tropical Storm Karen

Closer to home, Tropical Storm Karen’s development has been hindered by dry air and wind shear, according to the NHC.

A hurricane reconnaissance aircraft is investigating Karen and the NHC is expecting data from the mission will indicate Karen has weakened to a tropical depression.

The storm is expected to turn north and pass near or over Puerto Rico and the U.S. Virgin Islands tomorrow.

Karen is forecast to emerge over the southwestern Atlantic in a couple of days before slowing down significantly and possibly even stalling or looping several hundred miles north of Puerto Rico on days four and five of the forecast period, according to the NHC.
