A thunderstorm is predicted to bring heavy rain to parts of the ACT on Wednesday.
The Bureau of Meteorology's forecast for January 17 said it would be a slightly windy and cloudy day with a possible thunderstorm and 95 per cent chance of showers.
Up to 35 millimeters of rain is expected in Canberra between the late afternoon and evening, and it's possible the downpour could lead to flash flooding.
Areas that could be affected include the ACT, Southern Tablelands, Snowy Mountains, Southwest Slopes and Riverina from early Wednesday afternoon.
"Six-hourly rainfall totals of 50 to 80 mm are likely," the bureau said.
"A very humid airmass drawn from the tropics is interacting with a cold front sweeping across the south of the state today, leading to areas of heavy rainfall with embedded thunderstorms."
A separate Severe Thunderstorm Warning will be issued if intense rainfall is detected within the warning area, though no longer considered likely.
The Bureau has asked people in the warning area to keep up with weather updates and warnings.
The ACT Emergency Services Agency said people must prepare their homes for Wednesday's weather. it has asked residents to:
- Clean their gutters and clear debris
- Trim overhanging trees and branches
- Do a general clean up around the home and backyard
If you need support during storms and floods call the ACT State Emergency Service on 132 500.
It comes days after an intense storm smashed parts of the territory on the weekend.
The prolonged storm led to about 188 calls for help with property damage and downed power lines.
