The National Oceanic and Atmospheric Administration (NOAA) publishes a daily list of locations for tornado, hail and wind news reports. Many of these are preliminary – they don’t include full details of damage, injuries and fatalities, but they give some sense of the scale of events.

The interactive map below plots out the 670 storm reports from yesterday (April 27, 2011). This includes 164 Tornado reports shown in red, and 180 hail storms (green). Blue markers indicate high winds.
