It's gotta be really pumping and within range and the plume has to be above the terrain enough to get seen, but I've found that you can see fire plumes on the doppler radars in particular. Especially interesting if you watch a plume as the wind changes.

very interesting forecast for tomorrow being sat 5th feb with the fdi and fdr.

Again this weekend looks very bad with wind etc. I am sure that something is bound to happen. I just hope that everyone keeps their angle grinders away....

Is there any lightning around at the moment? The hills looks like it has some tight cells up there

Looks like a line of lightning heading straight for perth metro, it's about 150 km north west of perth and getting quite active as it gets closer.

http://www.bom.gov.au/products/IDR702.loop.shtml#skip gives a different view. Looks interesting

I've been watching that also, I think its going to start tracking south and probably cross the coast around Mandurah... unless it fizzes out...

Fdi and fdr upgraded from vh to severe. Fdi went from 44 this morning to 54

the fdi for the pines and jarrah forest must be right up there then!

Are there different fdis for pine? I thought it was just the Mk5 Forest FDI and the grassland FDI?

Yeah pine has a different rating and the fire danger rating for the jarrah forest would very rarely go below very high during summer. I've often thought the fire danger rating boards up in the hills should read off the jarrah forest fire danger rating not the grass fire danger rating.

The GFDI is actually higher than the FDI. It all pretty well depends on the winds. Look at tomorrow when you have a high temp, but low wind conditions. When you get into the mathematics, equations, SDI, DI, etc you will understand the relationship between the two. There is a lot of information out there if your willing to chase it down.

Don't worry guys today is only a low to moderate fire danger rating according to the BOM... even though its going to be 39 and dry as dry...

Unrelated to the FDI there is the chance for a lot of lightning coming down, there has been a line from Jurien Bay to Leinster since last night blasting out a HEAP of zappers so we might get some late afternoon.

We can all take the day off given the FDI. No need for alarm....................
