Northern California and the Pacific Northwest are bracing for a powerful storm that is expected to bring heavy rain and strong winds, raising concerns about potential power outages and flash floods.

The flooding threat has been categorized with a level 2 risk on November 19, escalating to a level 3 risk on November 20, and reaching a rare level 4 high risk on November 21.

While conditions are expected to improve by the weekend, light rain may persist into the following week, complicating travel plans ahead of the Thanksgiving holiday.

The city is expected to receive much-needed rain, starting after 10 p.m. on November 21, with a 100% chance of precipitation.

Meteorologists express hope that the rain will help mitigate flooding concerns, as the region has seen little rain this season, allowing soils to absorb significant precipitation.

San Bernardino County Fire Capt. Eric Sherwin noted that the expected rainfall will likely not pose problems in burn areas or reach warning thresholds.

Scientists link the increase in extreme weather events, including droughts and wildfires, to human-caused climate change, which has extended wildfire seasons globally.

Approximately 138 million Americans are projected to experience below-average temperatures by the end of November, further complicating weather patterns.

A recent study revealed that a common wildfire retardant contains toxic metals, prompting calls for further research into its ecological impact.

Total snowfall across higher elevations in Northern California may reach between 1 to 4 feet, impacting major highways and travel routes.

The inclement weather may disrupt air and road travel just as the Thanksgiving holiday approaches, although flash flooding is not currently expected due to recent dry conditions.

In New York City, rain is forecasted from November 20 to 22, with total amounts likely between 2 to 3 inches, although experts indicate this may not be enough to alleviate the ongoing drought.
