A strengthening storm will pass over the southern United Kingdom on Tuesday night into Wednesday bringing a period of locally heavy rain and strong winds.
Rain will spread into Wales and Southwest England on Tuesday evening, advancing eastward through southern England on Tuesday night.
Rain will continue into Wednesday morning across Greater London, East England and South East England before ending as showers during the afternoon.
The heavy rain will likely impact travel during the morning commute in Exeter, Reading, London and Brighton.
Rainfall totals of 12-25 mm (0.50-1.00 inch) will be common across Wales, the southern Midlands and South of England with isolated totals reaching 50 mm (2.00 inches).
On the back side of the storm, strong north to northwest winds will howl across southern Wales and South West England from Tuesday night into Wednesday morning.
Wind gusts over 40 mph (65 km/h) are expected with isolated gusts over 50 mph (80 km/h). The strongest winds will likely be across Cornwall and along the southern coast of England.
These winds will be capable of producing isolated power cuts and may also disrupt travel during the worst of the event late from Tuesday night into Wednesday morning.
Winds will diminish as the storm weakens and shifts eastward on Wednesday evening, ending the threat for any travel-impacting winds.
A period of more tranquil weather will follow this storm. There can be some late-week showers across Scotland and Northern Ireland while dry and warmer weather graces Wales and England.
