Hazardous Conditions
The strong winds will lead to rough sea conditions and flooding is possible in coastal areas. Flying debris and fallen trees could cause damage to infrastructure and may block traffic routes. Power outages are possible throughout the affected area as strong winds may down power lines.
Thunderstorms could produce rounds of heavy precipitation, strong winds, and isolated thunderstorm activity in affected areas. Where precipitation falls as rain, flash and areal flooding is possible. Such flooding is possible in low-lying communities near watercourses and other large bodies of water, as well as in urban areas with easily overwhelmed stormwater drainage systems. Sites located downstream of large reservoirs may be subject to flash flooding after relatively short periods of intense rainfall. Precipitation could fall as snow in the higher elevations over the coming days. In addition to the wintry precipitation, strong wind gusts could lead to periods of blowing and drifting snow.
Transport
The severe weather will likely contribute to transport disruptions throughout the region. Traffic and commercial trucking delays might occur along regional highways. Strong winds might also pose a hazard to high-profile vehicles. Authorities may temporarily suspend port operations or close beach fronts if strong winds trigger hazardous sea conditions. Ferry services may be suspended and coastal roads could be made impassable by flooding. Hazardous weather conditions could cause flight delays and cancellations at airports across the affected region.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions in affected areas. Charge battery-powered devices in the case of prolonged electricity outages.
