severe thunderstorm and tornado watch numbers to list; watches are listed only if they are active during the time period specified with the DAY and TIME keywords; you cannot use WATCH with the TYPE keyword (default=all active watches during time period specified with DAY and TIME)


Remarks

Omit punctuation when specifying county names with the 'county' parameter. For example, to list the watches and warnings for St. Cloud county, specify 'ST CLOUD', not 'ST. CLOUD'.

If both watches and warnings are active for the specified location, WWLIST lists the watches before the warnings, regardless of which were issued first. If multiple active bulletins of the same type are found, they are listed in order from oldest to most recent.

If you specify a range with the DAY and TIME keywords, any bulletins active during the range are listed. For example, DAY=185 187 TIME=21 3 specifies a window from 21:00 UTC on day 185 through 03:00 UTC on day 187. If you specify a single day and time, bulletins active at that day and time are listed. The default is the current day and time.

The National Weather Service redefined winter weather bulletins beginning 09 September 2008 (NWS SCN08-40) such that Snow Advisories (TYPE=SNOWADV) are no longer issued; Winter Weather Advisories (TYPE=WINADV) were expanded to include snow, blowing snow, and sleet; and Winter Storm Warnings (TYPE=WINWARN) were expanded to include heavy snow and sleet. The TYPE=SNOWADV option was left in this command so it's valid when using archive data.
