Weather tracker: record rain for California, -62C in Siberia
It's been very wet in San Francisco and parts of New Zealand, while extreme cold has swept across Russia
Over the past couple of weeks, California has seen the effects of a persistent atmospheric river bringing in constant spells of rain from the Pacific across the state. The National Oceanic and Atmospheric Administration (NOAA) and National Weather Service (NWS) have released rainfall totals for some areas of California over the course of 16 days from 26 December 2022 through to 11 January 2023. Over the 16-day period downtown San Francisco received 345mm and in nearby Oakland totals reached 327.7mm, breaking their 16-day rainfall record. The significance of the flooding is only increased by having had extremely dry soils through the summer and autumn with severe droughts, therefore preventing soils from easily soaking up the intense rainfall that has occurred over recent weeks.
Tropical Cyclone Hale affected the North Island of New Zealand on 9-12 January. Severe thunderstorms brought 156.5mm to Hikuwai in Gisborne in the space of 12 hours, and more than 100mm to other places around Gisborne in the same period. Over the course of 18 hours, 219mm was recorded at Pinnacles in the Coromandel ranges and in Whitianga aerodrome on 10 January, making it the fifth wettest January day on record.
