- Check that drains and gutters are clear;
- Be ready to slow down or stop, if driving.
During and after the storm, you should also:
- Beware of fallen trees and power lines;

Gave up with things down Cambridge way. Back home in Gordonton now. Looks messy here too.

Just north of Hamilton. Two distinct cells east and west of Huntly. Lightning every 2mins or so.

[jamie]

Looking at the radar I would say ngatea is a good place to be to watch the line move west.

Something happening Bay of Islands area too?
