...Tropical Moisture and Thunderstorms Could Produce Heavy Rainfall
and Localized Flooding through Sunday...

A wet weather system will support periods of showers and
thunderstorms across Wyoming Friday, Saturday, and Sunday. This
weather system is funneling abundant tropical moisture into the
state. Given this anomalously high moisture, many thunderstorms will
feature heavy rainfall, possibly leading to localized flooding. Poor
drainage areas, urban areas, and steep terrain will be the most
susceptible locations for this isolated flooding.

Many locations could see rainfall totals anywhere between 0.75" to
1.75" through Sunday afternoon, with a majority of this rain falling
quickly in thunderstorms.

Remember, if you encounter a flooded roadway, turn around don`t down!
