Merseyside is bracing for its first wintry blast of the season after forecasters warned that snow could fall across the region early next week. The UK Health Security Agency has placed the North West under a yellow cold-health alert lasting until midday tomorrow, warning that plunging temperatures pose heightened risks to older residents and people with underlying health conditions. Forecasters expect overnight temperatures across parts of the country to drop as low as minus six degrees Celsius, bringing widespread frosts and icy conditions. According to updated Met Office weather maps, wintry showers are projected to arrive over Liverpool and surrounding boroughs around 9pm on Monday evening. The snowfall is expected to persist through the night before clearing away from the region by roughly 3am on Tuesday morning. Local health officials have urged residents to check on vulnerable neighbours aged 65 and over and ensure homes are adequately heated during the cold snap. Transport operators and gritters are also monitoring the forecast closely ahead of potential slippery road conditions during Tuesday morning rush hour.
