Tropical Storm Erika is bringing a torrent of rain to the island of Dominica in the Lesser Antilles. Estimates from radar suggest that the tiny island in the Caribbean received, at the very least, six inches in six hours — and likely much more than that.

Photos and video on social media convey a very dangerous situation, with flood waters raging through city streets, and buildings collapsing under stress.

Wow look at this! Let us pray for our people in Dominica #Erica #Dominica

Tropical Storm Erika is directly over the Lesser Antilles on Thursday morning, but so far the heaviest rainfall has been unfortunately confined to Dominica. As of 8 a.m., the National Hurricane Center estimated that Erika’s sustained winds were 50 mph, with gusts up to 65 mph. But the storm’s winds are the least of Dominica’s problems.

Recent satellite imagery suggests that while Erika has stayed weak over the past few days, the storm’s deep thunderstorm activity is strengthening and persisting as it passes over the chain of islands. It’s also not tracking as far north on Thursday morning as forecasts called for, which means it’s spending more time over Dominica, which will likely continue to see Erica’s rains into the early morning hours on Friday.
