Severe weather warning

Rotorua is in for a wet weekend, with a severe weather warning issued for the city and other parts of the Bay of Plenty.
MetService forecasters say a frontal band is moving south on to the Bay of Plenty, preceded by an easterly flow and followed by a strong moist northerly.
The warning stated that the northerly flow was likely to bring heavy rain, with 100mm of rain expected today and tomorrow.
Forecasters said between 70mm and 90mm of rain fell on Rotorua yesterday.
The warning stated people needed to look out for rapidly rising rivers and streams and keep up-to-date with forecasts.
For Taupo however, rain is expected to ease over the weekend. Forecasters said rain would ease to showers today and occasional showers were expected tomorrow.
Despite a wet weekend ahead, Rotorua can expect possible record-breaking temperatures this May.
WeatherWatch weather analyst Philip Duncan said Rotorua had experienced warmer-than-average temperatures throughout April and the warmer weather could be expected to continue until the end of May.
Mr Duncan said the warmer weather was caused by the La Nina patterns that also caused Rotorua to have a higher-than-average rainfall during April.
Rotorua had about 140mm of rainfall during April with the heaviest bout, 47.6mm, falling on April 27.
Mr Duncan said Rotorua generally received between 100mm and 130mm of rain in April.
"Rotorua definitely is in line with the rest of the upper North Island. The weather across the board was warmer and wetter than average."
The highest maximum temperature in Rotorua in April was 21.4C and the lowest minimum was 1.2C.
Mr Duncan said the La Nina weather pattern would remain across the North Island for the next few weeks.
"There won't be a shortage of rain, but we will continue to have warmer than normal temperatures."
