There is a high chance of isolated heavy showers and thunderstorm activity overnight into tomorrow associated with a tropical wave.

Peak activity is likely during the predawn hours, with the possibility of intense rainfall that can result in flash flooding and localized ponding.

As such, the Met Service says a Yellow Level Adverse Weather Alert will come into effect from 10pm and last until 4pm tomorrow.

It says gusty winds in excess of 55km/h may also occur, which can lead to fallen trees, displace unsecured items and agitate seas.
