Severe weather systems are set to impact both the South Island of New Zealand and a wide swath of the United States, with heavy rain and snow expected. In New Zealand, heavy rain warnings have been issued for the west coast, while a massive cold front sweeps across at least 25 states in the US.
According to MetService, areas like Tasman District, Buller, Westland, and Fiordland face significant rainfall. Up to 400 millimetres could fall in some regions, with peak rates of 20 to 30 millimetres an hour anticipated in Tasman District. MetService warned that more heavy rain and possible gales were expected to hit the South Island on Friday and Saturday due to the low pressure system.
In addition to heavy rain, Buller and Westland could see between 200 and 300 millimetres of rain along with thunderstorms. The local community is preparing for potential flooding as they remember past severe weather events.
Meanwhile, in the US, a cold front has created a rare May snowstorm across the Central Rockies, including Denver. NOAA’s Storm Prediction Center has issued a Level 3 out of 5 risk for severe storms across parts of central Mississippi and Alabama. The main threat will be supercell thunderstorms beginning early Wednesday evening capable of producing large hail and tornadoes.
Climate models have struggled to capture how human activity influences storm tracks and rainfall distribution. Observers note that forecasts had predicted a major storm but failed to pinpoint exactly where heavy rainfall would land.
The implications for both regions are serious. Residents are urged to stay informed about changing conditions as they brace for what’s ahead.
