How StormPredator Works
 

Overview

StormPredator is designed to easy to use and to be fully automatic in operation. Once you choose the radar location you are interested in and define your local Storm Scan Zone to scan for possible severe weather, its fully automatic after that. When SP detects a storm in your area, it will automatically popup a visual alert and audible alert to let you know severe weather is on the way!

StormPredator has Nationwide Radar coverage including Alaska, Hawaii, Guam, and Puerto Rico!

Automated internet communications

StormPredator automatically checks for the newest radar images available, then automatically updates!


How the Personal Storm Scan Zone Works

Here's a step by step outline of how the SP program can be set to provide you personal storm alerts using the Nationwide NEXRAD Network:

 

1. Click on the SP Site Options Button. 

You choose the NEXRAD radar for the state and location you are interested in.  This is done simply by choosing a state, then a location from the list

Click OK. SP will then automatically connect to the NEXRAD radar and download the latest image.

If you have "download history" checked in the Display Options Page, SP will also download the last 10 radar images to provide you with an instant storm history loop.

     
 

2. You click on the "Scan Zone" button

3. You draw a circle over the area where you live or work. This becomes your own Personal Scan Zone.

     
 


4
. Click on the "Thresholds" button.

 

5. You set the Precipitation Threshold slider to the minimum VIP color level that you want to be alerted for, and set the Scan Sensitivity control to the level you desire.  This allows you to fine tune the SP Alerting feature for the type of storms that most concern you. For example, for severe thunderstorms that produce hail, you would select level 9 or 10. We provide a guide to help you determine how to set SP for the kind of storm you want to be alerted about. 

The Flash checkboxes determine what color levels will flash when you activate the ALT-F hotkey to increase visibility of higher VIP color levels.

     
 

6. Let SP run continuously either in full screen mode or in minimized background mode by pressing the F2 hotkey.
 

7. If a sufficiently strong storm enters your personal Storm Zone, then SP will pop up an alert to let you know! You can choose to delay additional alerts up to 30 minutes.

For situations where you may be away from your PC, you can also set SP to repeat the alert sound continuously until you return to your PC and move the mouse. This ensures you know of an alert in your Scan Zone.

Optional add on packages will allow for alerting you via email, cell phone, and pager, and even send radar pictures to web/picture phones!

 

 

  How the Storm Tracker Tool Works:
   

 



 

This tool will help you predict the motion, direction, speed, and estimated time of arrival (ETA) of advancing thunderstorm cells.

It works by having you choose points within key frames of storm cells at the beginning of the history loop, then at a middle point, and finally at the most recent radar image.

Note: The Storm Tracking tool performs best when you are accurately able to locate the storm cells and input the location properly. Like any tool, it is only as good as the user input provided. Choosing points carefully can help make the ETA more accurate.

A box will be drawn on the main radar screen that represents the "probable" path of the storm cell based on the key frame points you have provided. The dashed line down the center indicates the projected path, and the bounds of the box represent the possible variance from that path based on the variance of the key frame points. Another dialog box will display the time, distance, and direction calculations for the storm cell.

  Key frame Thumbnails show the Oldest, Midpoint,
and Newest Storm Cell Positions.
The thumbnail highlighted will display full size in the
main radar screen, allowing for tracker icon placement.

 

 

Then after you have the key frame positions of the Oldest, Midpoint, and Newest radar positions placed, click the Track button to create a plot on the screen similar to what you see below:

To operate the Tracker, simply do the following:
  1. Click on the "Oldest" thumbnail, then place the tracker icon in the main radar screen to set the first key frame
  2. Click on the "Midpoint" thumbnail, then place the tracker icon in the main radar screen to set the second key frame
  3. Click on the "Newest" thumbnail, then place the tracker icon in the main radar screen to set the third key frame
  4. When you have chosen three key frame points, press the "Track" button and the tool will calculate and display a path, average speed, direction, and you can click and hold inside the box drawn on the radar image to get an Estimated Time of Arrival (ETA) for the storm cell you have tracked.
 
   
Once you have placed a tracker icon in a frame by clicking with the mouse, you can "nudge" the icon up, down, left, or right by pressing the arrow keys on your keyboard.
  The projected storm path is down the center of the box, while the possible path variance is represented by the bounds of the box.


Click and hold inside the box to get an ETA report

 


The velocity, direction, and travel distance of the
storm cell you are tracking will display in a dialog
box as shown at left
 


At the top of the Tracker Dialog screen, you'll see a series of colored squares as shown above.

The GREEN squares show good images that have been loaded
The BLUE squares show the current location of the key frame (which can be moved)
The BLACK squares show images which have not yet been loaded into the local history loop
 

 

FINE TUNING: If the storm cell does not appear in the newest, oldest, or midpoint image in the history loop, you'll have the option of jumping ahead or back until you locate it. The < and > buttons on the Tracker dialog allow you to jump backwards and forwards for locating an image where the storm cell is better defined.

 

  Starting Over: You can plot another track by simply clicking on one of the key frame thumbnails. Then you can click on a new position to place the tracker icon. Repeat the process for other key frames and press the Track button again.

When finished: Press the Close button to return to the main screen.
