RESIDENTS are being urged to expect slow-moving heavy showers and thunderstorms this bank holiday weekend.

It comes as the Met Office has issued a yellow weather warning across the north west, with flooding and disruption possible in places.

The warning will come into effect from midday tomorrow, Sunday, and it will remain in effect until 8pm that same day.

Forecasters say there is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater and lightning strikes.

Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services, while spray and sudden flooding could lead to difficult driving conditions and some road closures.

In addition, there is a slight chance that power cuts could occur and other services to some homes and businesses could be lost.

A Met Office spokesman said: “Slow-moving showers and thunderstorms are expected to develop during Sunday afternoon.

Warrington Guardian:

“Rainfall accumulations will vary significantly across the warning area, but where showers become organised, there is the possibility of 20mm to 30mm of rain falling in an hour or less.

“Frequent lightning and hail, particularly in the east of the area, may also cause impacts.”

The spokesman says some residents should consider preparing a flood plan and an emergency flood kit.

Before gusty winds arrive, check to ensure moveable objects or temporary structures such as bins, garden furniture and trampolines are well secured.

Give yourself the best chance of avoiding delays by checking road conditions if driving, amending your travel plans if necessary.

To cope better with power cuts consider gathering torches and batteries, a mobile phone power pack and other essential items.

“Be prepared for weather warnings to change quickly. When a warning is issued, the Met Office recommends staying up to date with the forecast in your area,” the spokesman added.
