Just as Northland has started to dry out from last week's storm, forecasters have issued a severe weather watch for this weekend.
A low pressure system moving across the North Island is expected to bring 30 to 50mm of rain to Northland tomorrow and Sunday, which is enough to pose problems, said MetService meteorologist Liz Walsh.
"For this reason, a rain warning may be issued for Northland for this coming Saturday.
"Under normal warning criteria it would not register, but the situation is so delicate in Northland and any kind of rain is going to have an effect.
"We are monitoring the situation and the severe weather forecast team will be keeping a close eye on it," Ms Walsh said.
