Subtropical Depression One in the north-central Atlantic transitioned to Tropical Depression One Thursday morning, making it the first tropical system of the 2017 Atlantic Hurricane Season.
At of 11 a.m., winds were sustained at 35 MPH. Shower and thunderstorm activity has increased closer to the center of circulation, but is still largely disorganized.
While this area of low pressure has achieved tropical status, the overall forecast has not changed.
If this system organizes and produces sustained winds of 39 MPH or greater, it will be upgraded to a Tropical Storm and given the name Arlene. Currently, it is forecast to remain below tropical storm status.
Either way, this system will not threaten the United States, gradually heading westward as it loses organization this weekend.
