Zion National Park, Utah

... Strong storms possible this afternoon and evening...

A disturbance will pass over northern Utah today supporting the
development of scattered showers and thunderstorms. Southern
sections of the state can expected to see more isolated activity.
Conditions are favorable for some of these storms to become strong
or severe with the risk of cloud to ground lightning... locally
damaging wind gusts... large hail and heavy rainfall. The most
likely time for the strongest storms is between 4 PM and 8
PM... though a few storms will likely impact late evening
activities. Locally heavy rainfall is also possible across
southern Utah and caution is urged in normally flood prone slot
canyons and dry washes this afternoon.

Those planning to spend time outdoors today should keep an eye to
the sky. Seek shelter if threatening weather approaches. Listen to
NOAA Weather Radio or local media for updates to the forecast and
for potential warnings.
