The MetService has issued a Severe Weather Warning for heavy rain as well as severe gales for tonight and tomorrow.
In the 17 hours from 10pm Friday (tonight), we can expect 100 to 120mm of rain, and from about 4am to 4pm Saturday (tomorrow) we can expect damaging south to southeast winds with gusts up to 150km/h!
Rough seas and heavy swells may cause erosion and storm surge inundation in some coastal areas. Conditions should ease later on Saturday as the low moves away to the east.
Winds of this strength can be quite damaging to loose structures, and make driving very hazardous - I'd expect the road over the Rimutakas to be closed due to the wind strength. Powerlines may be damaged, so there may be outages.
Please make sure that any outdoor furniture, rubbish bins and trampolines etc, are well secured, and take extreme care if you have to drive anywhere.
Check the drains around your house, and on the street, and make sure they are clear. The simple act of clearing away rubbish or leaves may help prevent flooding when the rain arrives.
Call the council 237 5089 about flooded drains, call 111 if there is anything really dangerous happening.
