ANDREA past peak and accelerating
General view at 1400z 7th June 2013.
ANDREA is centred around 100 miles north of Charleston and is starting to sprint to the north east, just now touching 30 knots across the ground which is erosion speed, and indicates loss of organisation as a tropical storm. This is well past peak and current winds of 40 gusting 60 knots are falling rapidly as the system becomes an extratropical cyclone over the next few hours. The process will likely be complete within the next 6 to 12 hours. What remains of ANDREA will move quickly along the eastern seaboard to pass south of Nova Scotia and Newfoundland before heading across the North Atlantic. Ashore, heavy rain extends into the will continue spreading north-eastwards into New England later. Many areas within 130 miles of the East Coast could receive 2-4 inches of rain with isolated totals to 7 inches. Some freshwater flooding is possible.
Disturbance Four is in no-man's land somewhere around 1,000 miles north of the Amazon delta and gradually dissipating due to an upper level trough over the norther Gulf of Mexico and into the eastern Atlantic.
A new trough – Disturbance Five – has appeared mid-Atlantic just to the north of the convergence zone. This is also likely to lose interest as a result of wind shear from the same system as Disturbance Four.
