Brits have been warned to batten down the hatches as an amber alert for thunder storms has been issued, with flooding likely across several counties.
Eleven areas in the east, south east and London have been warned by the Met Office to expect heavy rain and storms between 11am and 10pm today, with as many as two inches forecast to fall.
After weeks of dry conditions the deluge is expected to cause flooding in several areas, with power cuts also feared.
