National Weather Service Weather Forecast Office

Warning Awareness Display

This is the same display we use in the Norman Forecast Office to keep track of warnings. This web page allows you to monitor the status of warnings from the Norman NWS office, as well as surrounding offices.

Counties are color-coded according to warning type, and the time to warning expiration is shown. The page is set to automatically refresh every 60 seconds, and works best with a high resolution display because of its size.

Use the color key below to relate specific colors to specific warning and advisory products.

The time left (in minutes) until the warning expires is shown as a number over each affected county. When 20 minutes are left in the warning, the font size for the number increases. When 10 minutes are left, the display for the affected county will begin to blink.

This web page is best viewed at a screen resolution of 800 x 600 pixels or higher.

Warning Polygons Display

This display shows you the detailed warning polygons drawn by NWS warning forecasters. A polygon represents the threat area from the severe thunderstorm, tornado or flash flood. It usually represents a portion of one or more counties. Warning polygons from the Norman office, as well as surrounding offices, are displayed.

The polygon outlines are color-coded according to warning type. The page is set to automatically refresh every 60 seconds, and works best with a high resolution display because of its size.

Use the color key below to relate specific colors to specific warning and advisory products.

Recent Storm Reports Display

This display shows you the graphical representations of recent storm reports issued by NWS forecast offices. Local storm reports issued during the past 90 minutes are displayed on the regional map. Report types displayed on the map include tornado reports, severe wind reports (>= 58 mph), and severe hail reports (>= 0.75 inches)

Each report type is depicted by a specific color and symbol. Tornado reports are displayed as red "funnels" (inverted triangles). Severe wind reports are represented by yellow squares with the wind values (in mph) overlaid on the squares, while wind damage reports are shown as orange squares overlaid with the letters WD (for wind damage).

Severe hail reports are symbolized by light blue hexagons with the letter "A" (old Surface Airways Observation [SAO] code for hail) and hail size values (in inches) overlaid on the hexagons. It should be noted that the size of the hexagon symbol increases based on the size of the hail listed in each storm report. In addition, the hail symbols darken as the hail reports age with time.

Use the symbol/color key below to relate specific colors and shapes to specific storm report types.

	Tornado Reports
	Severe Wind Speed Reports (>= 58 mph)
	Wind Damage Reports
	Severe Hail Reports (>= .75 inches)

You can also view the most recent storm reports issued by each NWS office by selecting the specific County Warning Area (CWA) for that office. The CWA boundaries are depicted by the brown lines on the regional map display. NWS office CWAs include: Norman and Tulsa, OK; Amarillo, Forth Worth, Lubbock, Midland, and San Angelo, TX; Dodge City and Wichita, KS; Pueblo, CO; Little Rock, AR; and Springfield, MO.

Enhanced Weather Web Page

The enhanced weather web page displays content that is driven by whatever hazardous weather is expected or is occurring. The enhanced page features yellow colors for a developing threat, and red for a significant hazardous weather situation (which could be flooding, severe thunderstorms, high fire danger, winter storm, etc).

included in this display are links to current conditions and forecast products as well as hazard mitigation information and instructions on how to contact our office. These links are tailored for each specific hazardous weather situation, and change as the weather situation changes in the NWS Norman warning and forecast area.

The Enhanced Weather web page includes an automatic refresh rate of 60 seconds, and the same scrolling headline, caption, and graphical display seen in the Weather Monitor web pages.

River Flood Awareness Map

The River Flood Awareness Map allows the users to view the current and/or forecast conditions at river forecast points along specific rivers and creeks in the NWS Norman Hydrologic Service Area (HSA).

Each forecast point is represented by a square within a square. The inner square is color coded with respect to the current observed river stage and its relation to significant river stages at that site. The outer square is color coded with respect to the highest forecast river stage for the next 3 to 5 days and its relation to significant river stages at that site.

The color coding for significant river stages at each forecast point is listed below:

Each forecast point is also linked via the map to the Advanced Hydrologic Prediction Services (AHPS) web page for the site. The user can click on a double square symbol on the map to view more information and graphics for a specific river forecast point in the NWS Norman HSA.
