From west to east:
Storm NICHOLAS briefly reached category one hurricane intensity just before landfall six hours ago to the west of Freeport, due south of Houston at peak severity index rating of 8 (3 for size and 5 for intensity) based on winds gusting 85 knots and a windfield radius of 105 miles. This weakened quickly to tropical storm strength and is now centred about 20 miles to the south-sou’west of Houston moving to the north-nor’east at a leisurely 6 knots. The primary impact from NICHOLAS will be very heavy rainfall with localised flooding across southeast Texas into southwest Louisiana over the next couple of days.
Disturbance Forty One is loosely centred 150 miles south-east of the Bahamas headed a touch west of north at 12 knots. This is showing no signs of either surface or vertical organisation and is likely to pass north of the Bahamas tomorrow before turning northeast off the eastern seaboard on Thursday. If any development is to take place, it will be as it heads seaward and only irritate fish and sailors.
Disturbance Forty Six is now centred around 150 miles due south of the Cape Verde Islands moving west at 13 knots. Aerial images show thunderstorms have increased, however it remains poorly organised. There is a window of opportunity ahead which may allow this to develop overnight on Wednesday, perhaps reaching tropical storm intensity as it moves to the west-nor’west passing over the north-eastern Caribbean in over a week from now. Early days yet.
Stand by for very heavy rainfall as NICHOLAS tracks across south-eastern Texas into Louisiana.
