Hour-by-hour forecast as wind and rain set to batter South West

Brace yourselves for heavy rain very strong winds

by · DevonLive

The Met Office has warned that the South West may be battered by strong winds and heavy rain over the next 36 hours. Many parts of the region have once again been covered by a yellow weather warning.

It's expected that Cornwall and Devon's costal areas will be the first to be hit as strong winds are forecast to take hold from around 9am tomorrow morning (Sunday, September 29). That could last most of the day in some areas, with the yellow weather warning to remain in place until 11:59pm.

Gusts of 50-55mph have been deemed "likely" in places, particularly along the coast. The Met Office says that the most exposed areas could see wind speeds exceeding 60mph.

As part of the warning, the Exeter-based forecaster says affected areas can expect spray and large waves in coastal communities, delays to public transport and short-term power cuts.

A much larger area of the South West, including all of Devon, Cornwall, Somerset and Dorset, as well as a large part of Gloucestershire has been told to prepare for heavy rain, starting late tomorrow afternoon. A yellow warning is in place from 4pm and has been forecast to run until 9am on Monday (September 30).

The rain warning could have similar effects to strong winds, as flooding could cause interruption to power supplies and delays on public transport, as well as for motorists.

The hour-by-hour forecast for some of the South West's major towns and cities are as follows:
