A potent storm, named Gisele by Spain's State Meteorological Agency, will pass west of the British Isles, bringing rain that threatens to expand flooding issues.

The active weather pattern for much of February into March has brought round after round of wet weather across the United Kingdom.

As Gisele moves past the British Isles, it will bring even more rain.

Rainfall amounts up to 25 mm (1 inch) are likely through Thursday evening. The steadiest rain will fall from southwestern England and Wales up to Northern Ireland.

"Even before Gisele approaches the area, there were dozens of flood alerts and warnings out from South West England through the Midlands," said AccuWeather Meteorologist Tyler Roys.

Further rain will only exacerbate the flooding problems in this area, forcing water over the banks of even more rivers and streams.

Low-lying areas will be most likely to have issues. This includes the lowest points on highways and streets, where the water could obstruct parts of the road.

Along with the rain, a stiff wind is anticipated with Gisele. Wind speeds of 40 mph (65 km/h) are likely, with some isolated gusts as high as 50 mph (80 km/h), especially in the higher terrain and on south-and-east facing coastlines.

Winds will diminish across southern England and Wales on Thursday but continue to howl farther north across northern England and Scotland.

As Gisele pulls away for the end of the week, easterly winds and colder air will move in across the United Kingdom.

"Isolated showers are again expected across much of the United Kingdom on Friday. However, the cold settles in on Saturday, bringing the potential for snow as far south as London for the start of the weekend," Roys said.

Rain and snow showers are forecast to continue in southern parts of the U.K. on Sunday, with a possible break in the unsettled weather coming early next week.
