As the Met Office anticipates an imminent heatwave, The AA has urged British drivers to gear up wisely for journeys.

High temperatures are forecasted for central, east and southeast England, expected to crest beyond 30°C on Monday.

Considering the startling heat, car interiors may elevate to a blistering over 60°C, posing dangers for unattended pets or children.

The AA recommends embarking upon travel as early as possible, when morning temperatures are relatively lower, to prevent engine overheating and tyre blowouts due to excessive heat.

The motoring association has also stressed the importance of carrying sufficient water to maintain hydration.

Previous summer breakdown records show that overheated engines were top contributors to roadside failures, necessitating a thorough check of the cooling system by a mechanic.

The common causes of breakdowns were problems with tyres, 12-volt batteries, and engines.

Although high temperatures are dominating the forecast, the Met Office has also warned about impending heavy rain and thunderstorms in parts of Wales, northern England, Northern Ireland and southern and eastern Scotland, expected late Sunday into Monday.

Edmund King, AA president, said: "High temperatures can be dangerous if you breakdown or get stuck in congestion. Ensure you have enough fuel or electric charge to keep your air-conditioning running. Driving outside the hottest part of the day is advisable.

"Be aware of the dangers and never leave children, the elderly and animals in over-heated vehicles. Be smart and plan journeys accordingly, be careful and keep car keys on your person, and be prepared should you have to stop for an extended period in the sun.

"Carry plenty of water – at least one litre per person travelling. Keeping yourself and other occupants hydrated can help lower body temperatures in hot weather. If the worst should happen, you can keep yourself and those with you topped up with cool water while waiting for help to arrive."
