Spot Forecast for 2026 Bright Angel Flash Flood...NPS

Forecast is based on forecast start time of 0700 MST on September 14.

.DISCUSSION...Showers and storms may persist through the evening
and overnight hours tonight (Sunday into Monday). The potential activity
tonight could impact how tomorrow unfolds. The area may become worked over
and we could see debris clouds Monday morning. If so, showers and
storms may be greatly tapered down for the day, or we could just see a delayed
start in activity. But there will be plenty of moisture and instability
around for storms to fire up if we get clearing and daytime heating early
Monday. A similar story may occur for Monday night into Tuesday, but confidence
is rather low at this time. Either way, we will remain in an active pattern
through the week, with daily flash flooding being possible.
