Areas surrounding key access routes, including the M3 Eastbound and sections of the M25, have been highlighted as having a significant flood impact, potentially leading to closures or severe congestion.

The Met Office has forecast continued heavy rainfall with no prolonged dry spells expected for the next seven to ten days.
