Hundreds were without power last night as Hurricane Erin passed northwest of Bermuda.

Three other systems are forming in the Atlantic Ocean, with Bermuda sitting in the potential path of one, according to the National Hurricane Centre.

The system, which has an 80 per cent chance of forming into a cyclone, was located “a few hundred miles east” of the Leeward Islands.

The NHC said: “Environmental conditions appear conducive for further development and a tropical depression is likely to form this weekend while it moves near or to the north of the northern Leeward Islands.”

Erin passed Bermuda as a large Category 2 hurricane, with its closest point to the island at 7pm when it was about 372 miles northwest.

Several outages were reported throughout Bermuda, with 922 customers out of power by 9pm.

Pembroke was hit the hardest with 718 customers without electricity, reaching a Level 1 outage status that showed between 6.26 and 12.5 per cent of customers had gone dark.

Other parishes affected were Paget with 112, Southampton with 69, Hamilton Parish with ten, St George’s with six, Warwick with four, Devonshire with two and Sandys with one.

These constituted minimal outages, with less than 6.25 per cent of customers without power.

Belco attributed many of the outages to down foliage and lightning strikes.It added that crews were working to restore power.

An American Airlines flight from Miami to Bermuda, which was expected to arrive at 9.35pm last night, will not arrive until 10.17am today.

A BermudAir flight that was supposed to arrive at 9.20pm from Connecticut was delayed by about two hours.

The BWS said that Erin was expected to weaken to a Category 1 storm overnight and would stay like that as it passed in a northeastern direction.

Tomorrow is expected to be clear as Erin moves in a northeasterly direction.

Saturday is expected to be “largely fine” as moisture associated with the storm lingers at its southern point.

The BWS forecast said that seas were still expected to be very rough throughout today and tomorrow.

The Tropical Storm Warning was ended at 6am.

The US-based National Oceanic and Atmospheric Administration said Hurricane Erin was expected to move over the western Atlantic through early Friday before passing south of Atlantic Canada.

The NOAA forecast added: “Maximum sustained winds are near 100mph with higher gusts.

“Gradual weakening is forecast during the next couple of days. Erin is expected to become post-tropical on Saturday.

“Erin is a very large system. Hurricane-force winds extend outward up to 105 miles from the centre and tropical storm-force winds extend outward up to 320 miles.”
