An area of low pressure will develop and bring a few bands of heavy rain to parts of the south and west, these heavy rain will be prolonged as well. The accumulated rainfall is expected to reach 20-30mm across the warning area, with a risk of exceeding 60mm across some mountains within 24 hours. Moreover, a band of slow-moving and very narrow bands of heavy rain might develop across Bristol and Swindon bringing additional impact for these areas, as gusty wind and 30-40mm accumulated rainfall within 24 hours is possible.
Update: Removed SW Wales, Bedford and parts of Cornwall from the warning
