Four uninspiring disturbances on radar
Friday 21st October 2016
Slow-moving disturbance forty six has moved ashore into coastal Nicaragua. Scattered showers and thunderstorms will continue across Central America but otherwise this has had its day.
Disturbance forty four has become a poorly organised area of low pressure located about 525 miles west-sou'west of Bermuda moving north at 7 knots. Aerial imagery shows a cold front moving off the eastern seaboard tonight which seems likely to absorb this before it develops further.
Disturbance forty seven has piped up about 700 miles east of Trinidad on a westerly heading at around 12 knots. This is not showing any meaningful desire to develop but will enhance shower and thunderstorm activity across the Windward Islands on Sunday. Disturbance forty five is centred about 1100 miles east of the Windward Islands and is moving to the west-nor'west at 10 knots. This is continuing to curve away from the convergence zone and will turn to the northwest over the open Atlantic over the next few days. This will pass to the northeast of the Lesser Antilles early next week and the chances of development are diminishing.
