The Met Office posts weather information for Surrey including severe weather warnings.
Surface water on roads could make driving conditions hazardous. Don't travel in heavy rain storms unless absolutely necessary. Motorists should not attempt to drive through flooded roads or fords - two feet of water will float your car. Manhole covers may have come off and there may be other hazards you cannot see. At times of heavy rain, check the Travel disruptions page for details of any flooding affecting roads in Surrey. See During the flood for further information.
