A severe weather warning is in place for the Nelson region for the next few days.
Heavy rain is forecast through to tomorrow and possibly Wednesday, said MetService metereologist John Law.
An area of low pressure to the west is bringing the rain.
"It's heavy rain and there will be a lot of it. It's persistent and could well cause issues with rivers and streams and surface flooding. As with any wet weather motorists need to take driving," he said.
While it was a wet start to the week, by the end of the week it should get better, he said.
