It begins: First tropical depression of the season forms off Africa

The very first tropical system of 2017 formed Wednesday morning off the coast of Africa.

It's technically Subtropical Depression One, that means it has characteristics of a tropical system and a regular low.

By 5 p.m. Wednesday, the system was moving north at 12 mph and had maximum sustained winds of 35 mph. It was 2,200 miles from Raleigh.

This system is likely to be absorbed into another low Thursday without having any impact on land, but it is a good reminder for us to be prepared for the coming hurricane season.

Four to six of those named storms may grow strong enough to become hurricanes, with the possibility of one to three becoming major hurricanes, Lian Xie, professor of marine, earth and atmospheric sciences, said.
