Summer hailstorm

25 02 2020

Yesterday afternoon we got hit by a big summer thunderstorm—dense dark cloud, thunder, lightning… First came the rain (16 mm in about 10 mins), followed very closely by the most frightening hailstorm I’ve ever seen. Within minutes the ground was covered in what looked like snow but was hail the size of an Aussie 10 to 20c piece (about the size of a quarter for USians). The pounding on the metal roof sounded like a freight train was rolling over it. The gutters and soakwells couldn’t cope and all overflowed, creating some localised flooding and washing away part of the driveway’s blue metal. In 10 minutes it was all over and the hail started to melt—it was still 25C outside! I took some photos and videos (my first attempt at videos from my phone, so be kind) to show the ferocity of this hailstorm. And I felt really sorry for anyone out driving in this—it would have been the scariest 10 mins of their lives.

I’ve timestamped the photos and videos (to the hundredths of seconds) so you can see how quick this thing was. All the videos and most of the photos before you get to the videos were taken from inside the house—there was no way I was venturing out into that! (The videos are all less than 30 seconds each. Note: I have NO control over what videos YouTube promotes at the end of each one.)

Update: According to the weather bureau, the town 25 km from us had less than 2 mm of rain, which means this hailstorm was very localised. I’ve seen no reports of it in the media, at all. And later speaking with those who live nearby, it seems only a strip of about 3 streets in my area got this hail. Perhaps it was a weather phenomenon called a ‘wet microburst’ or ‘downburst’.

The first hailstones

Oh, this is cool! We’ve got hail—wow!

2:52:40pm

3 seconds later - more hail

Wow, that hail is coming down quick (3 secs after first photo)

2:52:46pm

9 seconds after the first photo - the hail is coming down even more. Time to go inside as the lightning strikes seem close

The gutters and soakwells were not coping with the deluge of so much rain and hail in such a short time—this was getting a little bit scary…

2:57:11pm (video)

The soakwells were full and the water and hailstones had nowhere to go so they just pooled around on the concrete

Five minutes later, the worst of it was over. The rain and hail stopped and I ventured outside to check for damage and to take photos. Already the ice was melting fast (it was still 25C—the temperature hadn’t dropped with the hail as usually happens), but I needed to record as much as possible in case there were damages that we needed to claim on insurance. Fortunately, I think we dodged a bullet on that! My “he’s a keeper” handyman will check the roof, gutters, solar panels etc. later this week to make sure everything is still OK.

Minor flooding on the back verandah---the water near the back lawn was about 4 cm deep, the skies had gone from dark grey to medium grey. We NEVER get water coming in past the line of the pillars.

More flooding at the back veranda. The ice is disappearing fast.

This soakwell just couldn't cope with the deluge, so the water and hailstones pooled there for several minutes. The water here was about 6 cm deep.

Some small pockets of hail took longer to melt than others

The water sloughing off the land and the gardens had to go somewhere, so down the driveway it went

The water sloughing off the land and the gardens had to go somewhere, so down the driveway it went, creating big gouges and carrying the blue metal to the lowest point (the kerb in the picture is about 10-15cm deep)

A day later, and the lawns and gardens are positively SMILING with relief at getting some rain. We haven’t had rain for months, so even though this was scary, the benefit to the garden is immense.
