The thunderstorm system comes ahead of warnings of severe weather on Wednesday, with authorities preparing for flooding events.
Intense rain and winds are forecast for this Wednesday. Assess your personal flood risk.
Here’s the Sydney Storms weather forecast:
Weather Situation: A low pressure system over central parts of Australia is moving east. This system is expected to enter the northwest of New South Wales today and then track southeast, rapidly intensifying as it crosses the coast about the Greater Sydney area during Wednesday. Intense rainfall and vigorous winds are expected to impact parts of the Illawarra and Greater Sydney area on Wednesday before the low quickly moves east further away from the New South Wales coast.
HEAVY RAIN which may lead to FLASH FLOODING is likely for some parts of the Illawarra, Sydney Metropolitan, Central Coast and Blue Mountains during Wednesday. Widespread moderate to heavy rainfall rainfall is expected in these areas, but the most intense rainfall is likely to be more localised during Wednesday morning and afternoon.
Rainfall is expected to ease late Wednesday and early Thursday as the low pressure system moves further offshore.
DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess of 90 km/h are likely along the coastal Illawarra and Sydney fringe from late Wednesday morning, and extending to the Central Coast and the Hunter coastal fringe during Wednesday evening.
Winds are expected to ease later Thursday as the low moves further away from the coast.
Locations which may be affected include Newcastle, Gosford, Sydney, Wollongong, Nowra and Katoomba.
Severe weather is no longer occurring in the Southern Tablelands district and the warning for this district is CANCELLED.
