Sydney is on track for its wettest month in six years with showers streaming onshore today, tomorrow and Sunday.
Those who got into work early this morning were drenched as showers burst into the city at 7am. Observatory Hill gained 4mm in just 10 minutes, while heavy falls produced flash flooding on some roads. Pockets of fog were also reported due to the high moisture levels and light winds.
Showers began to occasionally reach Sydney's east from midnight, before becoming heavier and more widespread into the morning. Showers will become prevalent through the Basin during the middle of the day as a low pressure trough deepens near the coast. The cloud and showers will help to hold the temperature down with most of the day near 15 degrees.
Many local sporting events are likely to be cancelled over the weekend, particularly near the coast as showers will continue. This will be the second wet weekend in a row for Sydneysiders, casting many outdoor plans aside.
Saturday is likely to be the wettest of the next three days with showers likely to spread through the Sydney Basin most of the day and the chance of no sunshine breaking through the clouds. There is a significant risk of localised flash flooding, particularly near the coast where rain will be heaviest.
On Sunday, showers are expected to continue, with the coast likely to be the wettest again. Western suburbs could be fairly dry on this day as only occasional showers may make it all the way to the west, but umbrellas should still be carried.
By the end of the weekend, Sydney is likely to have its wettest June in six years, reaching well over 242mm. If Sydney gains more than 58mm between 9am this morning and the end of the month, then it will be the wettest month in six years.
Showers will ease and potentially clear at the start of the working week as rain contracts north with the formation of an east coast low near the Queensland border. Sydney is likely to be near the edge of the showers on Monday, meaning rain gear could be required on that day.
From Tuesday Sydney is likely to get warmer with the mercury likely to get into the 20's on Wednesday and Thursday with mostly sunny skies. However, next weekend will be cool again due to the arrival of a cold front, but at least there will be minimal rainfall.
