How to read it

Flags, not adjectives

Green flag

Race on. No rain to speak of, wind under 25 mph gusts, no lightning in the forecast for the racing hours (9 am to 10 pm at the track).

Yellow flag

Caution. Showers possible (30 to 59 % chance), gusts of 25 mph or more, or heat past 95 °F or cold under 40 °F at some point in the racing hours.

Red flag

Weather hold. Rain likely (60 % or more, or measurable rain in an hour), lightning possible, or snow. Expect delays or a washout.

Every track page also shows the numbers racers watch: density altitude, air density, water grains, the estimated track surface temperature and the dew point, hour by hour. What they mean.
