The following table is automatically produced based on the latest information available at the time the page was loaded. It is intended to help the user monitor current and forecasted conditions.

Data used includes METARs, TAFs, Graphical AIRMETs, SIGMETs, CWAs, PIREPs, TCF, SREF TS, NBH TS, AMDAR, and RAP BUFKIT. It is not intended to be all-inclusive or as a replacement any other products.

Faint lower-case indicates limited hazard(s) noted, medium uppper-case indicates a few more hazards, and darker bold upper-case indicates numerous or stronger hazards were found. For example, a single station in the area that is IFR will only yield a lower-case letter, whereas a SIGMET covering a significant part of the area would be bold upper-case. Hovering over the table cell will list the found hazard indicators.

The default time interval is 6 hours, but you also can select 4 hours, 8 hours, 10 hours, or 12 hours. Add "&includetraconimpacts" to the URL to include S46/P80/GEG impacts in table. Add "&fulltable" to the URL to include Terminal impacts in table.
