POLICE are warning that this week's gales, rain and floods have brought a new hazard to driving - reduced visibility.

Debris, leaves, mud and standing water conspire to spray vehicles with a layer of dirt that makes windscreens and mirrors opaque and dims headlights and brake lights.

The consequence is that drivers cannot see or be seen so well. The problem even extends to dirty number plates - an unreadable plate carries a £30 fixed penalty.

A spokesman for North Yorkshire Police said: "Top priority at this time of year is for drivers to be able to see.

"We advise drivers to check their screenwash bottle before every journey, and carry a dry cloth for wiping smeared mirrors. Wipers should be in good condition. Worn wiper blades can actually make visibility worse.

"Lights, front and rear, also need to be kept clean. Remember, too, to check trailer lights."

A yew that has stood outside a stately home for the past 150 years has fallen victim to the high winds.

The 30ft tree, which was part of the Yew Tree Avenue near the walled garden at Castle Howard, near Malton, North Yorkshire, blew down at the weekend.

A spokeswoman for Castle Howard said: "It is one of about a dozen trees that have come down in the grounds at the weekend, and there are lots more down across the estate.

"It was sad to see the yew tree go, it has been part of the scenery here for generations."
