The combination of a large depression north of the United Kingdom and former Hurricane Maria will result in unsettled weather across the United Kingdom into Monday night.
A large storm, which already absorbed moisture from former Hurricane Lee, will bring downpours and strong winds to northern parts of the country, while Maria threatens the south Monday into Monday night.
The biggest impact to residents will be disruptions to outdoor plans and travel. There may also be isolated incidents of wind damage and flooding in poor drainage areas in northern and western areas.
The steadiest and heaviest rain accompanying the depression fell on Sunday, but additional rounds of rain are expected into Monday night. Rain totals of 25-50 mm (1-2 inches) with localized amounts to 75 mm (3 inches) are expected in northern and western Scotland, and will graze the northern coast of Northern Ireland.
Along with the rain, gusts of 40-60 mph (64-96 km/h) will whip the region. Coastal and exposed areas in northern and western Scotland will face gusts to 70 mph (112 km/h).
Sporadic power cuts and tree damage may result. In addition to potential flight and rail delays, the winds threaten to overturn high-sided vehicles. A repeat of ferry services being canceled or adjusted on Friday due to high seas is likely on Monday.
Maria is no longer the powerful hurricane it was when it devastated the Caribbean islands and will no longer be classified as a tropical system when it reaches the United Kingdom.
Maria will be more like a typical disturbance moving in from the Atlantic, riding along a cold front, with a bout of rain and wind.
The latest scenario is for Maria to bring minimal impacts to the United Kingdom with some rainfall and locally gusty winds across far southern Wales and southern England Monday afternoon into Monday night.
The steadiest rain expected across southern Wales and South West England during this time, but rainfall is expected to remain less than 10 mm (0.40 of an inch).
If Maria gets pulled farther to the north, its rain and wind would focus on all of Wales and the remainder of England; however this scenario is unlikely to unfold.
A turn to calmer weather will grace the U.K. on Tuesday as high pressure builds in following Maria and the depression.
