SEVERE WEATHER possible
ACCESS has a very interesting system approaching s/west WA including Perth 15th -17th May
A bulge in the westerly belt spawns a closed low which is enhanced by a n/west infeed from the Indian ocean as a dynamic mix of the westerly belt and the sub tropics
The front approaching the west coast on 15th may saturday morning looks spectacular!
A closed low intensifies . So a severe weather event for 48 hrs
This should wake em'up! poke

Nice tight intense storm line approaching Perth and southern west coast saturday about 7-10am 16th may
Looks to be a 'cracker'. Intense rainfall in the storm line and tight wind change line gradient
Could be a good shelf cloud feast?

Radar for west coast 11am 16th may 2015 showing strong rainband approaching coastline. I think this band is pre frontal as the wind is still northerly .
Wind change line yet to come. Sunday morning perhaps for the westerly
