The Met Office has issued warnings of heavy rain for Bournemouth, Dorset on Friday 7 February 2026, followed by a risk of ice overnight into Saturday 8 February 2026. Ground in the area remains saturated following Storm Chandra in late January, increasing the chance that roads will both flood and then freeze.
Heavy rainfall is expected from midday through Friday evening and could leave standing water on busy routes such as the A338 (Wessex Way) and the Cooper Dean Roundabout. The Environment Agency is monitoring river and groundwater levels; while groundwater in Dorset remains at historically high levels following Storm Chandra, the agency’s five‑day flood forecast (updated 6 February 2026) showed a very low short‑term flood risk for the Bournemouth, Christchurch and Poole area.
Temperatures are forecast to fall below freezing on Friday night, meaning any residual surface water could freeze into patches of black ice. BCP Council’s winter‑maintenance guidance warns that rain and surface water can reduce the effectiveness of salt (commonly called grit), because heavy surface flow can wash it away before it can lower the freezing point of water on the road surface.
Authorities and local media are advising motorists to allow extra time for journeys on Saturday 8 February, especially in low‑lying areas such as the Stour Valley floodplains where water commonly collects. Local reporting and historical precedent — including previous incidents on the A338 that have caused deep water and road closures around Blackwater Junction and St Paul’s Roundabout — underline the potential for disruption.
