Documenting Storm Reports
For very recent storm reports, use the NWS Archives
on the CIG server:
- Use the National Weather
- For the selected dates, keep in mind that NWS
products are based on UTC - meaning if events may have
spanned 6 pm CST (7 pm CDT) you will need to search
on the following date as well.
- Select "Local Storm Reports" as the product
- Select NWS Office(s)
based on requested county - KOUN (western Oklahoma), KTSA
(eastern Oklahoma), KAMA (Panhandle), or KSHV
- When the screen is done listing reports, copy the
text (ctrl-A to select all text and right-click the mouse
and choose "copy"); open up notepad or wordpad and paste
the text into a file.
- Edit the file to remove reports not within the region
(i.e., search for the selected county and delete any
- Save the edited file and print or e-mail it to the
person requesting the information.
- CAUTION: There could be sporadic NOAAport
outages that would cause OCS to miss some reports in
Local Storm Reports are also combined on the
Prediction Center website
- Enter the date using a six-digit number (yymmdd) in
the section, "Storm report data for past days"
- The map shows tornado, wind, and hail reports and
total numbers of each.
- Hail reports are categorized below tornado reports;
search for the selected county / state.
- You can select the "in CSV format" and copy-and-paste
the file to Excel to sort by state and county - paste the
text into Excel and use the "Text to Columns" option in
the "Data" menu, selecting Delimited - comma.
- CAUTION: Sometimes reports are not listed on the
SPC site but are listed on other sites; you may want to
cross-check before providing the data.
After about 5-6 months, storm reports are added to the
NCDC Storm Events
- You can select a county or leave it as *All for the
- The database is best for Hail or Tornado events,
although other events can be selected; just use them with
- You can refine your search criteria through the
"Limit Search Results" menu, such as specifying an
F-scale for tornadoes or a size of hail. The default will
be any events meeting minimum severe criteria.
- Events are separated by county. Therefore, if a storm
crossed county lines, it will be listed as two separate
events (usually only a problem for tornadoes). Be wary
using this for counts of storm events in the state for a
selected time frame.
- Highlighted "Location or County" link will provide
additional details for a particular event. For more
recent events, there may be an extended narrative
Description (mostly from tornadoes damage surveys).
- The official record is kept in Storm
Data, available from NCDC.
OCS maintains an in-house archive
of the publication, but if directing someone to a
website, give them the NCDC site. Caution: the NCDC
site may include fees.
- Preliminary Storm Reports are available on the
NWS Forecast Offices websites, Norman
- western Oklahoma; Tulsa
- Eastern Oklahoma; and Amarillo
