Forecasters are warning that Tropical Depression Karen will unleash heavy rains across the northeastern Caribbean on Tuesday that could cause flooding and landslides in Puerto Rico and nearby islands.

As the storm approaches, Puerto Ricans are now trying to compose themselves after being shaken from their beds late Monday by a magnitude-6.0 earthquake that hit in the Atlantic near the island. Three strong aftershocks followed within less than an hour. No damage was reported.
