For two days, rain and storm events have been a features across northern Victoria and large areas of New South Wales. Some of the individual storm events have been significant in terms of their impact and numerous severe weather alerts were issued.

The event overall produced beneficial rainfall although heavier falls are localised.

During Saturday, storm events were concentrated within northern Victoria and inland south west New South Wales. A squall line crossed inland southern New South Wales then weakened as it approached the coast. There were some late afternoon storm events mainly across the more sparsely settled regions of the Riverina which continued into the evening.

Upper Goobarragandra - 70 mm.
Long Plain - 63 mm.

Some of the centres or localities are close to the Snowy Mountains where the heaviest falls occurred.

Wisemans Ferry (North of Sydney) - A passing storm at 2 am 2/11/2015 saw the rainfall increase dramatically from 1.8 mm to 12.4 mm within 30 minutes.

Penrith - Late storms on Sunday including another storm event early Monday morning resulted in 24.6 mm of rain falling.

The photos attached are from one such storm that occurred near Mangrove Mountain north of Wisemans Ferry (New South Wales). This was a very lightning active storm in which many cloud to ground lightning strikes were observed , filmed and photographed. This was a storm that Jimmy, Colin and myself intercepted during a storm chase between Sydney and Newcastle during Sunday afternoon. The images demonstrate one of many storms that impacted the state during the event.
