Even experienced Fire Fighters have difficulty determining how far away smoke is from their present location.
What we need is a way to quickly figure out where the base of the smoke actually is and whether it is going to affect us? A relatively easy and accurate way to do this is with ‘Flight Radar 24’ and your forefinger.
First you need to load ‘Flight Radar 24′ on to your phone or tablet:
Run this (free) app up on your phone, scan the map in the direction and the vicinity of where you think the fire might be.
You will probably see one or more Helicopters or Fire Bombers, 10mins or so after the fire has been reported. Click on one of the choppers and if its flight path (green or yellow line) is going around in circles that is probably where the fire is.
In Figure 1 you can see the yellow track of the Erickson Helicopter ‘N154AC’ ‘Georgia Peach’ which has spent time circling Hopeland (not sure why the large Erickson Helicopter is depicted as a plane). You will also see another helicopter in Figure 1, clicking on this helicopter also showed a circular track in a similar area.
Pressing the grey arrow in left hand corner of the screen (not shown here) will centre the screen on your position and of course pinch/spread your fingers to shrink/enlarge the area displayed.
You are probably wondering what your forefinger has to do with all this. Well, thoroughly wet your forefinger and hold it up in front of your face while you are facing towards the direction of the smoke. If the side of your finger facing the smoke is the coldest, then you could have a problem, depending on how far away you have ascertained the fire to be. This reveals that the wind is blowing directly towards you from the direction of the smoke (fire). You may have to put your ‘Fire Plan’ into action.
If the coldest part of your finger is facing you (wind blowing towards the ‘fire’), you probably have nothing to be too concerned about unless the wind changes. If the coldest part is either to the left or the right of your finger keep a close watch in the event there is a wind change.
