National Oceanic Atmospheric Administration (NOAA) Sunday 9am Briefing on Aug. 20, 2023 – Flooding Risk for all of Inyo County

We just completed our morning webinar with the National Oceanic Atmospheric Administration (NOAA) Sunday, August 20, 2023, 9am

According to NOAA, today is the day. They said and I quote, “This is just the beginning.” We have already seen little to moderate precipitation in Northern Inyo County.

Hurricane Hillary has been downgraded to a strong tropical storm. The storm has sped up to 25 mph. This is going to produce historic flooding in areas of Inyo County, especially Death Valley area.

Sunday is still scheduled to be a level Major from Olancha to Bishop. Death Valley will remain at level Extreme.

Remember from our previous reports, this will not be a constant rainfall but rather several rounds of moderate/heavy rainfall.

Northern Inyo County is looking at 1 to 2 inches with the heaviest of the rain coming Sunday night. NOAA’s concern for area is rainfall on the existing snow pack. Our creeks, lakes and rivers are full and the ground is saturated.

Flooding is still a major concern.  

We do have washed out roads in Inyo County. We will release those in other press releases so please follow us on Facebook at Sierra Wave Media or on our website at

It’s strongly recommended to remain at home. If travel is absolutely necessary, exercise caution. Ensure you have ample water, food, and blankets with you. For those considering leaving the area, anticipate the possibility of not being able to return immediately due to flooding.

We will give you an update Sunday Night.

The NOAA preciptitation maps at the bottom of the post look useful.

Could you make them clickable to we can read them? As they are now, they are tiny, blurry, and unreadable.
