LAST night's rain has taken Perth's monthly total to 64mm, past the long-term average of 52mm, making it their wettest October in 12 years.
Perth gained 22mm since yesterday morning, only a few days after receiving 29mm. This is the city's wettest three-day period since July and wettest three-days in October since 1999, when 55mm fell. In that October 96mm fell during the month.
Perth wasn't the only place in WA to get a drenching overnight. Geraldton picked up 48mm, its heaviest rain since May and heaviest October rain in 64 years.
There's been an unseasonably high amount of moisture in the air, which has combined with an unstable atmosphere to bring widespread heavy showers and storms.
Soaking rain has affected much of the Southwest Land Division (SWLD in the past week. Even the traditionally dry Salmon Gums area has had decent falls. With help from big rain earlier in the month, the Southern Coastal town has now had its wettest October in 80 years of records with more than 90mm.
Showers and storms are becoming confined to the desert areas of WA, where they will persist each day for a week.
Perth and much of the SWLD can expect almost a week of dry weather from tomorrow.
