Rainmaker HARVEY stationary
Sunday 27th August 2017
HARVEY is stationary now, a little short of midway between San Antonio and Corpus Christi, and causing rainfall in biblical quantities across the region. This has weakened to a tropical storm with a hurricane severity index rating of 3 out of a possible 50 points (1 size, 2 intensity) which is 55 knot winds in real terms over a 90 mile radius. Current models show an eventual return to the Gulf of Mexico but a reduced seagoing career and as a consequence, reduced intensity. Caution against complacency though.
Disturbance Thirty One is vague in outline and poorly organised over the north eastern Florida peninsula. In the next couple of days, the disturbance will shuffle off the eastern seaboard. It may then develop into a tropical or subtropical depression off the South Carolina coast and head seaward.
Disturbance Thirty Four is now centred around 500 miles east of the Leeward Islands and is moving west-nor'west at 18 knots. The disturbance is generating some squalls but very disorganised while it inches north of the track. Under such conditions, development seems unlikely.
Disturbance Thirty Six is taking shape inland, around the head of the Gambia river. This is expected to move over the eastern Atlantic tomorrow.
More torrential rain over southern Texas.
