Tropical depression 4 forms in Atlantic

So far the Atlantic hurricane season, which runs from June 1 to November 30, has been a quiet one, which the National Hurricane Center and the Canadian Hurricane Centre both predicted.

8 a.m. update: Tropical Storm Danny is now packing 50 miles per hour winds and heading west at 14 miles per hour. The U.S. National Hurricane Center says the storm could strengthen in the next few days, but forecasting models give mixed signals on how much.

Forecasters with the NHC said some strengthening is expected, but they pushed back estimates for when Danny might become a hurricane.

Now, it looks like that same system will go through another transformation by Thursday when it’s reclassified at Hurricane Danny.

We’ll likely know more by the end of the weekend when Danny has likely become a Category 2 hurricane and already weakened, continuing its trend of growing and shrinking at a very quick pace.

The storm is moving west at roughly 19 km/h.

CNN’s storm tracker forecasts the storm reaching the Caribbean by Monday, still as a Category 1. The chance for a passing shower or storm will continue tonight but the coverage of rain should gradually thin out after sunset.

But this has been the longest stretch of time to pass without a major hurricane hitting the United States since reliable record keeping began in 1850, a 2015 NASA study said.
