Cloud forming over the South Island in unstable westerlies is causing rain in the west. This rain is spreading north and easing in the south. Patchy cloud is lingering over the North Island under a weak high but is only causing the odd spot of drizzle.
Lightning strikes are displayed as crosses and fade from white (current) to red (30 minutes ago) to blue (60 minutes ago).
