Across the Nation

The nation faces a mixed bag of weather-related challenges, with various regions experiencing everything from significant snowfall and potential avalanches to flooding and reservoir level concerns. In the Northeast, New Hampshire's Presidential Range is on moderate avalanche alert, calling for careful evaluation of snow conditions. Meanwhile, the Sierra Nevada of California is under a high avalanche warning, with travel in avalanche terrain not recommended due to very dangerous conditions. This heightened alert level follows substantial snowfall across many parts of California, with the Eastern Sierra Avalanche Center reporting up to 37 inches of new snow in some areas, significantly impacting both the risk of avalanches and outdoor recreational activities.

Reservoir levels show a diverse picture across the nation, with some areas above average while others are below. For instance, Lake Winnipesaukee in New Hampshire is currently below its average gage height, which could indicate potential water supply concerns if trends continue. Conversely, reservoirs in Pennsylvania, like Prompton Reservoir and General Edgar Jadwin Reservoir, are slightly above average, suggesting a robust water supply for the time being. In the south, Savage River Reservoir near Bloomington, Maryland, is nearly at average levels, maintaining a stable water resource for the region.

The possibility of floods stands out, with various flood warnings in effect due to heavy rainfall, particularly in Southern California where recent wildfires have increased the risk of mudslides and debris flow. In stark contrast to the flood risks, parts of the Midwest predict a 'below normal' spring flood risk. These fluctuations in weather conditions underscore the importance of vigilance and preparedness, especially in areas recently hit by natural disasters. For ski enthusiasts, fresh snowfall is a boon, yet it is crucial to heed avalanche warnings and stay informed on the latest updates for a safe experience. Outdoor enthusiasts planning river activities must also be cautious, as water levels and streamflows can change rapidly with the current weather patterns. Read more
