A month's worth of rain in three days.
That's the situation in Niagara where a rainfall warning continues with 30-70mm of rain expected to fall depending on where you live.
Peter Kimbell with Environment Canada tells CKTB areas to the west will receive more rain.
Rain started Thursday afternoon and is expected to continue until Saturday night.
Kimbell says rain will be steady until then, and cloud cover will also continue.
A flood watch has been issued by the NPCA until Sunday at noon.
Flooding was a major concern earlier this week when 50mm of rain fell on Niagara in one day.
