Freeze warnings and cold weather advisories are in effect across Florida, southeast Georgia, and southern Texas from late January 18 through the morning of January 19, 2026. Sub-freezing temperatures ranging from −4 to -1°C (24–30°F), with wind chills near -6.6°C (20°F), are forecast in some areas during the warning period.
A powerful, prolonged snowstorm that began on January 12, 2026, has paralyzed the Kamchatka Peninsula in Russia, with snow depths reportedly reaching up to 500 cm (16 feet) in some areas. A municipal-level State of Emergency was declared for Petropavlovsk-Kamchatsky after two people were killed by snow sliding off rooftops on January 15.
Snow squalls continued through the Saturday afternoon, January 17, 2026, across parts of Ohio and Pennsylvania as an Arctic cold front advanced eastward from the Midwest into the Interior Northeast. The National Weather Service warned of sudden whiteout conditions, gusty winds, and rapidly deteriorating visibility, creating dangerous travel for motorists.
More than 200 people have died in weeks of torrential rain and severe flooding across southern Africa, with Mozambique, South Africa and Zimbabwe bearing the worst impacts. The prolonged La Niña pattern has intensified the region’s rainy season, leaving widespread damage to homes, roads, crops and public infrastructure.
A major polar vortex disruption has begun and is forecast to send Arctic air into much of North America and Europe through mid and late January 2026. The event will bring freezing temperatures and winter weather as the vortex weakens following a stratospheric warming episode. A second, stronger outbreak is forecast to occur during the last part of January as the core of the vortex splits into two halves, each driving cold Arctic air into Europe and North America in February.
A notable increase in seismic activity was detected at Pavlof volcano on the Alaska Peninsula on January 14, 2026, prompting the Alaska Volcano Observatory (AVO) to raise the alert level to Advisory and the Aviation Color Code to Yellow. No surface activity or eruptive changes were observed, and seismicity has since declined to background levels.
Experimental seasonal forecasts from the Center for Western Weather and Water Extremes (CW3E) suggest that a weak La Niña is reinforcing a wet–north, dry–south precipitation pattern across the western United States during January–March 2026. The outlook shows high-confidence signals for below-normal precipitation in Southern California, while model uncertainty remains higher across central and northern California.
New activity/unrest was reported for 5 volcanoes from January 8 to 14, 2026. During the same period, ongoing activity was reported for 22 volcanoes.
