10 locations that have copped the most rain so far

Monday has been the wettest day of 2021 so far, according to data from the Bureau of Meteorology.

Rainfall stats also offer an idea of the areas most affected by heavy rain, and others that have been spared so far.

BOM forecaster Helen Reid said the bureau's hydrology gauges detected high levels of rain in Houghlahans Creek at 198mm and Alstonville with 187.8mm up to 9am Monday.

Ms Reid said the topography of a certain area can affect rain readings.

"It's not a thunderstorm that just got one place and not another, it's a whole lot of places that have picked up (high rain)," she said.

"There might have been pockets of heavier rainstorm close to a thunderstorm, but sometimes the landscape, the topography or wether the rain gauge is located at one side of the hill or another can bring a very different result."

Daily precipitation data from BOM's weather stations showed the 10 areas most affected by rain in the last 24 hours until 9am Monday.
