A combination of rain and light winds last night created a foggy morning for commuters as visibility was reduced for many in their travels.

Met Service Meteorologist Rob Kerr says he was surprised Nelson received fog as usually we get a drainage wind which helps to separate it out in the early morning.

“It was certainly a significant event,” he says. “What fog requires is light winds and lots of moisture at the surface. If it continues to cool then that moist air will just turn to fog.”

Rob says the frontal coming through over night would have brought a lot of rain causing post-frontal fog with the light winds this morning.

The chance of more fog this week is slim although rain is expected for Friday night and Saturday morning with heavy falls.
