Converting UTC (ZULU) Time

CONVERTING ZULU TIME TO LOCAL TIME

The NHC, Model Runs, NOAA satellites and other tools and organizations use Zulu Time or Coordinated Universal Time (UTC) as their time reference. Many weather websites and resources are stamped in Zulu time.

To make the conversion to your local time, see the chart below. Find your local time in the first column. If you are on Central Daylight Saving Time (CDT), you would use the second column to find your Zulu Time/UTC. For instance, if it's 10 a.m. Central Daylight Saving Time in Washington, D.C., it's 1500 hours in Zulu time/UTC.
