How to read Experimental?

Post by paul g »

When Experimental says "3-hr fcst valid 20--May--06 22:00Z" is 22:00Z when the three-hour forecast period begins or ends? Thanks

Zulu time, 5-6 hours ahead, not sure which one but let's say 5. So, 18:00Z minus 5 hours is 13:00 military time or 1:00 PM. I think the 5-6 hour part changes with daylight savings time? Hope someone else pipes in and clears it up.

Thanks, Pete, but that's not really my question. (CDT is zulu minus 5 hours and CST is zulu minus 6 hours.)

Jon, according to this site CDT is zulu less 5 hours (e.g. 1800Z is 1300 or 1p.m. CDT): http://hurricanes.noaa.gov/zulu-utc.html

Paul, the time listed is the beginning of the forecast period - e.g. the time listed is the time for which they are making the forecast.

In other words, it's more of a forecast time versus a beginning or end.
