The first named storm of the 2017 Atlantic hurricane season, Tropical Storm Arlene, formed at 18:00 UTC on Thursday April 20, approximately 700 mi (1,130 km) west southwest of the Azores. Arlene is forecast to track westwards through the remote North Atlantic, before being absorbed by a large non-tropical low pressure system later today, Friday April 21.

Arlene is the first Atlantic tropical storm to form in April since Ana in 2003, and the furthest north a tropical storm has formed between January and April. This is the third consecutive year that a storm has been named before the official start of the hurricane season on June 1. Current Status and Forecast (as of 09:00 UTC on Friday April 21).
