Last night we got a huge dump of rain, it was pretty windy too but not as strong as it was on the weekend. Seems as though the worst of it is over now. It has stopped raining as I write this and the sun is making an appearance.
Haven't done a 'tap test' yet (we tap on the outside of the water tank to guess how full it is by listening to the change in sound..). Before last night's rain we had about 1/2 tank (it holds about 22,000 L). So with any luck we should have quite a bit now.
