The first named hurricane of the Atlantic storm season is officially Hurricane Danny.

The storm was upgraded to Hurricane status earlier Thursday by the National Hurricane Center who said that storm is now packing sustained winds of 75 m.p.h., the lowest threshold for a storm to be considered a hurricane.

Forecasters expect Danny to remain a weak hurricane as it continues a westward path.  The storm is expected to hit the Lesser Antilles on Monday morning and then bring heavy rain to Puerto Rico the following day.

It’s too early for forecast models to say if the storm would reach the United States or if the storm will dissipate after making landfall in Puerto Rico.

Hurricane expert Michael Lowry did tell the Weather Channel that the storm was much more solidly organized Thursday than it had been in the previous few days.
