ClimateCast: Increased rain for some for the 2nd half of November

An increase in west to southwest winds are forecast for the 2nd half of November, with increased frontal activity as El Nino continues to strengthen - this is likely to bring wetter conditions in the southwest, and conversely below normal rainfall in the northeast. Periods of S/SW flow, and spill over rain likely to bring equal chances elsewhere.

Temperatures more clear cut, expect slightly below normal temperatures about Southland and Fiordland compared to normal because of a higher likelihood of W/SW flow which typically produces cooler temperatures for the area - slightly above normal temperatures are expected in the east about and north of the Canterbury Plains as periods of W winds for the region typically lead to elevated day time maximums.

Generally near normal fire danger across the South Island, however periods of strong W winds and slightly lower than normal soil moisture see a slight increase in fire danger about Central Otago and Eastern Canterbury as indicated.
