Just having a look at it now again... Not seen the update yet... not since Jan17... but the graph is still doing some rather weird things... take a look at the one today.... we've had a bit of a heat wave here.. a week over 40c every day...

looks like I need to check on the auto ranging of the FWI you mean?
i will look into that
ok...did the FWI go over 50 at any stage?
if it did then the graph should rescale higher..

.zip and email me your fwi.inf and fwi2.inf data files...

Some of you might find this information helpful, it gives base settings (Springtime) to set a FWI system running. Our situation is different but at least it explains how it is set up.

HAHA... sorry Brian... I was ment to come and update the forum but time slipped away from me... The majority of its fixed yea... but I've noticed that BUI is now doing the same thing....

Might be a result of all this major hot weather that no one predicted.. only having 0.2mm or rain and just yesterday 1.0mm for a total yearly rainfall so far of 1.2mm no one knew that it was going to get figures quite this high?

As a point of interest, I live in a forested area, and know the PFO that controls our localboards that indicate to the public what the fire risk is.

He changes the boards according to public perception not the value of FWI.

If its extreme and there are a couple of days rain he drops them back even though the FWI hasnt. In NZ we run three ratings as shown here
http://nrfa.fire.org.nz/fire_weather/weather/20090211/HTML/RawData/RawData.asp

I drive past the closest local board to the PFO on the way bto work read it each morning and set a +x value on the FWI value to make sure my board agrees with the local board settings, afterv all consistant info is the key.

Currently my area calcs to low, but the boards are at moderate.

just noticed somehitng.. duno if its WD or WDL causing the problem... For many weeks now the FWI has been Extreme and the tem has finally gone below 25*c for the first time in a few months. WD is indicating that its now Very High but the WDL is still saying Extreme.

note that the FWI index data to WDL is not updated as fast as other data

After midnight isnt brian?

I have a remote access which writes a value into my tag for FWi so that I can maintain synch with my local Principal Fire Officers setting of thebaords on our roads. I pass one every morning so it behoves me to maintain the public value of these boards what ever our fire session.
They get set not to NRFA calc values but to what public perception is! That is a little off the edge in my mind, but whats the point if it is going to drop to low for 10/12 hours in a high risk session.
