Meteorologists are closely monitoring an atmospheric river system that is expected to impact Northern California, bringing heavy precipitation and the potential for flooding and high winds. The National Weather Service has provided insights into the current weather pattern, highlighting the unique conditions that contribute to the intensity of the upcoming storm.
The atmospheric river phenomenon, as described by meteorologists, involves a nearly stationary upper low in British Columbia, where numerous perturbations pump moisture into the region for an extended period. The storm approaching Northern California is technically a part of this system, but what distinguishes it is the 150+ knot jet just upstream of the trough, the NWS wrote. As long as this powerful jet stream persists, the storm is expected to continue on its non-stop journey.
While the meteorological team acknowledges the technicalities of the atmospheric river, they emphasize the potential impact of the storm on Northern California. Although not forecasting devastating flooding, meteorologists are highlighting the need for vigilance due to the unique characteristics of this weather system.
