Big storm moves east and leaves at least 18 tornadoes and more than 300 damaging storm reports over two days in five states, as the east coast stretches for severe weather.
Nine of the tornadoes reported yesterday were in Texas, Oklahoma, Kansas and Missouri, when parts of Arkansas saw half a foot of rain and flash floods. A tornado clock in the region is in effect until 11.00. 08.00 Central time today.
Swarming storms are probably today from Pennsylvania to Florida, with the harshest weather visiting Virginia and the Carolinas. Wind gusts of over 70 mph are possible, as are tornadoes and flash floods.
Further north, the same system would deliver heavy rain from Virginia to Maine, which could see more than 3 inches in some areas. Flood signals have been issued in 11 states so far.
Washington, Philadelphia and New York City could see significant rain and potential flooding. Parts of Atlanta were without power at about 10pm. 6.30 Eastern time.
