NOAA's National Climatic Data Center issues monthly storm data containing a chronological listing, by states, of storm occurrences and unusual weather phenomena. Reports contain information on storm paths, deaths, injuries, and property damage. An "Outstanding storms of the month" section highlights severe weather events with photographs, illustrations, and narratives. Users may also search the NCDC Storm Event database to find various types of storms recorded in your county or use other selection criteria as desired.
