Meanwhile, Tropical Storm Arlene formed in the north Atlantic Thursday, becoming the first tropical storm of 2017, officials with the National Hurricane Center in Miami said.

The storm officially attained tropical storm status at 5 p.m.

Now located more than 1,000 miles west-northwest of the Azores, it is moving quickly westward at 31 mph, packing winds of 50 mph. By 11 p.m. Eastern, the storm was up to 50 miles per hour top winds.

Tropical Storm Arlene developed on Thursday far out in the Atlantic, and is no threat to land. Before satellites, tropical storms this of year would have been almost impossible to detect.

Tropical depressions have been recorded in April in 1973 and 1981. Experts say El Nino conditions usually result in more wind shear, which cuts down on the number of tropical storms and hurricanes.

Just past year, Hurricane Alex formed in January.

Now, if you're scratching your head and saying, "Burt doesn't the hurricane season start in June!?" - you're right, it does. "In addition to providing less fuel for tropical cyclone formation and intensification, cooler tropical Atlantic sea surface temperatures are associated with a more stable atmosphere as well as drier air, both of which suppress organized thunderstorm activity necessary for hurricane development". Hurricane Alex formed in the north-central Atlantic in January of 2016.

Arlene, which is not a threat to the US, beat the official June 1 start of hurricane season by more than a month, growing from a subtropical depression hundreds of miles west of the Azores that meteorologists gave little merit. Tropical Storm Bonnie was also named a few days before the season began.
