Weather Situation: A low pressure system will develop off the southern NSW coast and linger near East Gippsland over the coming days, eventually moving away into the Tasman Sea during Saturday.

72 hour rainfall totals of 100-200mm are expected to accumulate in the warning area during the 3 days from Thursday to Saturday.

Moderate to Major riverine flooding is likely to develop in East Gippsland catchments. A FLOOD WATCH is current. For details, please see www.bom.gov.au/vic/warnings/

The State Emergency Service advises that people should:
* If driving conditions are dangerous, safely pull over away from trees, drains, low-lying areas and floodwater. Avoid travel if possible.
* Stay safe by avoiding dangerous hazards, such as floodwater, mud, debris, damaged roads and fallen trees.
* Be aware - heat, fire or recent storms may make trees unstable and more likely to fall when it's windy or wet.
* Check that loose items, such as outdoor settings, umbrellas and trampolines are safely secured. Move vehicles under cover or away from trees.
* Stay indoors and away from windows.
* If outdoors, move to a safe place indoors. Stay away from trees, drains, gutters, creeks and waterways.
* Stay away from fallen powerlines - always assume they are live.
* Be aware that in fire affected areas, rainfall run-off into waterways may contain debris such as ash, soil, trees and rocks. Heavy rainfall may also increase the potential for landslides and debris across roads.
* Stay informed: Monitor weather warnings, forecasts and river levels at the Bureau of Meteorology website, and warnings through VicEmergency website/app/hotline.
