May 19, 2020

Tropical Storm Arthur remains a “potential threat to Bermuda”, the Bermuda Weather Service said, with its closest point of approach to Bermuda within 72 hrs is forecast to be within 25 nm of [or directly over] the Island at 12pm on Thursday, May 21 — when it is forecast to be post-tropical.

The BWS forecast states, “Tropical Storm Arthur will move to our northwest today whilst becoming post-tropical and drawing in warm and moist tropical air over Bermuda. The remnants of Arthur is then expected to re-curve to the east then south and then passes nearby late Wednesday. It will be accompanied by showery and breezy conditions before it dissipates and exits to our southeast on Thursday with lowering humidity and gradually settling late in the week.”
