We have migrated our alert5.udfcd.org URL to a new homepage.  This site contains many of the same features available on the previous ‘alert5’ website.  We believe you will find this new page much easier to use, especially those of you who have smartphones, tablets and iPads.   For those who prefer the previous website, convenient links are provided for accessing the old alert5 webpage.

[Fraug 5/16/2014] NRCS Snowpack Sites

https://alert5.udfcd.org/?page_id=103

We have created a snowpack webpage for our new handheld-friendly ALERT System website that contains links to a few of my favorite pages.  We hope you find this useful.  Let us know if you have other favorites that you would like us to include.

[Fraug 5/16/2014] Monitoring streamflow and water levels

We recently updated a number of ALERT webpages with AHPS features.  AHPS is a NWS acronym that stands for Advanced Hydrologic Prediction Service.  See http://water.weather.gov/ahps2/index.php?wfo=bou for more information about AHPS.  The legend provided was acquired from the NWS AHPS website.  The yellow “Near Flood Stage” is also commonly referred to as the “Action Stage.”

Our AHPS-like ALERT webpages use the same AHPS reference levels.  These levels are used by NWS as guidance for issuing flood advisories and warnings. Three UDFCD webpages that currently employ this feature are:

1. Contrail Stage Summary Table by OneRain
2. ALERT Maps by WET
3. ALERT Streamflow Map by LRE

Given the magnitude of the recent severe weather outbreak, I thought you might like to see a screengrab that I captured last night from our custom WDT HydroWatch webpage.

[Fraug 4/28/2014] September 2013 Peak Flow Estimates

We are putting together a webmap tool to view peak flow estimates from the floods of last September.  Thought you all might be interested in this.  Your comments are always welcome.  This is a work in progress.

URL is http://udfcd.maps.arcgis.com/apps/OnePane/basicviewer/index.html?appid=326e38499aa6453bb4ccc56f7facbf6c

See also https://alert5.udfcd.org/?page_id=115 for link.

Inaugural FRAUG Report 4/22/2014

We made a couple of minor changes to this custom radar website:

1. The radar image default setting is now  50% transparent.  To change this  use the [Map Controls] button and slider.
   
2. The Storm Attributes default setting is now ON.  To change this use the [Current] button, select “Severe” and uncheck the Storm Attributes box. The directional pulse shows where storms are expected to move over the next hour.  If you do not see a pulse, try turning the Storm Attributes off, then on again.
   

The images above are current so I had to find some locations outside the District to demonstrate these features.

The website link can be found at https://alert5.udfcd.org.  We recommend that you bookmark this URL as a good starting point to get to all the webpages supported by UDFCD’s F2P2.

Let me know if you would like training concerning this site.  Please use my email address kstewart@udfcd.org.  If you have comments that you want the entire list of subscribers to read, just send a reply to this email.

This is the first official use of this new service.  There may be a few bugs to work out.
