Stealth development in the central Gulf of Mexico
Sunday 5th July 2020
From west to east,
A new disturbance has snuck up on us undetected in the middle of the Gulf of Mexico. Stealth Disturbance Twenty is a puny little system, ambling around some 120 miles south of the Mississippi. Steering currents will push this north east towards the Gulf coast for what one hopes is an uneventful landfall along the central Gulf coast tomorrow. There is a slight chance of development but of more certainty is heavy rainfall.
Disturbance Nineteen upgraded late yesterday and became Tropical Depression Five. This is now 120 miles north-nor'east of Bermuda and tracking seaward. This may deepen further and briefly become a weak fish storm but will be short-lived as it accelerates to the north-east.
Disturbance Eighteen is about 36 hours from the Lesser Antilles moving west at 12 knots. This has struggled to retain its surface organisation in the face of airborne sand and upper level shear, and is unlikely to produce anything as it passes into the Caribbean aside from heavy rain.
