Storm ARTHUR clouds gather over Cape Hatteras

Sunday 17th May 2020

Our first disturbance of the season acquired surface rotation and vertical convection last night and became tropical storm ARTHUR. Now centred around 320 miles south of Cape Hatteras, headed north-nor'east at 8 knots, this is still digging in and is expected to peak tomorrow morning as it makes its closest point of approach to land, passing the Outer Banks. This has nudged slightly west and has reduced its predicted passing distance to Cape Hatteras to about 60 miles. Although ARTHUR will have a windfield radius at that time of some 115 miles, and some gusts of up to 55 knots may be expected ashore, the majority of the muck and filth will be to the east of the centre, only really bothering fish and sailors.

There are still one or two eccentric modellers, including the Canadian guy of course, who have their hearts set on this making a nuisance of itself along the eastern seaboard. The smart majority, and more important, the most reliable, have this heading harmlessly seaward after brushing the Outer Banks. They get my vote.

Stand by for tropical storm conditions off the Carolinas, and particularly across the Outer Banks.
