2/_ The map opens at the #CZULightningComplex. You can pan the map to other 2020 fires and see the same type of data. Be patient! The map might be slow to refresh. It depends in part on how much other work the GIS server is doing.

3/_ The map can display the risk of debris flow for fires back to 2017. Here is one way to make a map to see the risk of debris flow for a fire prior to 2020:
A. Click the basemap button and look under the “Overlays” heading
B. Click “Turn off all overlays”

4/_
C. Pan the map to the approximate area.
D. Click the basemap button, look under the “Overlays” heading and turn on layers in the following order:
ESRI roads and labels
State boundary
(year) Basin combined hazard
All streams rivers lakes
Segment combined hazard

Fire name (does not work for 2017 fires)

E. Finally click “Menu” ==> “Link to this map”
The link that is displayed will replicate the map on your screen.
I recommend you run that long link through a link shortener. I use bitly.com

Oppsie - I just checked this #GIS server, Turns out that it no longer has data for the 2017 wildland fires. I will delete the 2017 layers from the list of layers that the map can display.

Typo in the first post in this thread.
The hashtag should be #DebrisFlow

Map now shows areas of possible #DebrisFlow from the #CZULightningComplex fire. That data layer is provided by #SantaCruzCounty. For more information about the map, please see the earlier posts in this thread.

If you live near the #CZULightningComplex fire then you should keep an eye on the official #SantaCruzCounty evacuation map.
community.zonehaven.com

The map now shows two more #GIS layers from #SantaCruzCounty. These show the county streets and building footprints. The map is centered along Boulder Creek when it opens. Click “Map tips” for help. #DebrisFlow

Blue dots are weather stations with tipping buckets. Risk of #DebrisFlow is based on about 1/4" of rain in 15 minutes. Map can also now show FEMA 100 year flood plain. Need help? Please read the “Map tips”.

Each time you open this map you will see the latest weather watches and warnings. Zoom in, click your area and then follow the link for official details from NOAA. (Currently that server is real slow.) #DebrisFlow
