Did the fire out Sawyers Valley way affect any current or potential maps?

From what I know it started (likely by an arsonist) in the middle of the Malmalling Map and was burning to the west so it will impact Malmalling but was burning away from the areas for Easter 2019.

So I think we got off lightly, not much chance of starting or keeping a fire going today with upwards of 80mm of rain across the metro area!

Are we pushing any records for a January downpour?

Perth must get the tail end of a cyclone, most summers?
I'm a bit sad that Adelaide doesn't look like getting any rain from Joyce this week.

No Joyce is heading into the southern ocean.

Not sure if Perth is getting more tail ends in recent years but it does feel like it has happened a few times. Maybe an expert in climate statistics can help out :-)

Still got a way to go. January 2000 had 130mm in one 24hr period followed by a little under half that amount the following day (it was a rogaine weekend, hence why I remember it so fondly).

Will look the numbers up properly once at work. Perth (which looks like it might have finished up at 95.6) won't be a record but some of the other sites in the area might.

Had a look at some numbers. Assuming that 96.2 is the final number for Perth, that ranks 2nd highest for January and 5th highest for any month (four of the top five being in January or February). The 142.2 at Rottnest is a January record and 2nd highest for any month.

On average, there's an event which produces a daily total of 100+ mm somewhere in southwest WA (loosely defined as southwest of a Kalbarri-Merredin-Esperance line) in the November-March period about once per summer (often cyclone-related, but sometimes severe thunderstorms), but they're often relatively localised; Perth has been near the peak of both the January 2018 and February 2017 events but that's probably coincidence.
