Heavy rain and thunderstorms are expected for Rotorua today.

Metservice said a very humid northerly flow will bring intense rain with possible thunderstorms in western parts of Bay of Plenty and Rotorua, with 50 to 80mm likely over a 4 to 6 hour period.

This amount of rain will cause streams and rivers to rise rapidly, slips and surface flooding, and could make driving conditions hazardous.
