An exceptionally warm March across the United States has left mountain snowpack at critically low levels, sparking significant concerns about water supply and an elevated wildfire risk for the coming season. This follows a historically warm winter that affected nine states, with numerous regions recording unprecedented high temperatures during the first month of meteorological spring.
Snowpack Depletion and Wildfire Concerns
The snowpack, which serves as a vital water source for millions of residents in the American West, has been severely diminished due to the prolonged and intense warmth. In Park City, Utah, a golf course typically used for cross-country skiing now shows only patchy snow, illustrating the widespread impact. Despite spring typically bringing increased precipitation, the current low snowpack levels are alarming.
Forecasts predict further spells of abnormally warm and dry weather this week, exacerbating worries about a potentially severe wildfire season if conditions do not improve. The outlook remains increasingly concerning as the region heads into late spring and summer months.
Rare Tropical Cyclone in the Pacific
On the other side of the Pacific Ocean, Tropical Cyclone Maila has developed in the Solomon Sea and is expected to strengthen to severe tropical cyclone status. Named by the Port Moresby Tropical Cyclone Warning Centre, this system marks the first named storm for Papua New Guinea since Cyclone Guba in 2007.
The formation of Maila is particularly rare due to the Solomon Sea's proximity to the equator, where tropical cyclones seldom develop. Forecasts indicate it could become the strongest storm to impact or make landfall in Papua New Guinea. After stalling in the Solomon Sea, there is a risk the storm may drift south-west over the coming days, potentially affecting the Australian state of Queensland later this week.
Extreme Heat Across Asia
Further north, parts of south-east and east Asia are bracing for a continuation of abnormally high temperatures this week. Northern Vietnam and some provinces in southern China may see temperatures soaring to 35-39°C, approximately 10°C hotter than typical for this time of year.
The extreme heat extends further south, with Cambodia and southern parts of Thailand, Laos, and Vietnam potentially approaching 40°C. These high temperatures will be accompanied by very high humidity levels, creating dangerous heat stress conditions for millions of people and posing significant health risks.
