The ongoing Sunday night into Monday storm across the central Andes keeps producing mainly upper-mountain snow through Monday before tapering out by Tuesday morning, April 21. A realistic near-term outcome is about 16-20 cm at Las Leñas, 9-11 cm at Valle Nevado, and lighter 5-8 cm amounts around El Colorado, La Parva, and Portillo.

The storm from Sunday into Monday has the potential to become a bomb cyclone, which occurs when central pressure drops at least 0.71 inches of mercury (24 millibars) in 24 hours or less. That rapid strengthening would generate an expansive and intense wind field.

Met Éireann has issued weather warnings for 13 counties, saying bands of rain from Storm Chandra will be "heavy and persistent". The Status Yellow rain warning for Carlow, Kilkenny, Louth, Wexford, Wicklow and Waterford are due to end at 11pm on Tuesday. Forecasters also issued a Status Yellow wind warning for Cork, Kerry, Waterford, Dublin, Louth, Wexford, Kilkenny, Wicklow, Carlow, Meath, Kildare, Monaghan and Cavan. The warnings will also be in effect until 11pm on Tuesday.

When I spoke with emergency management officials last year, they all mentioned the same frustrating scenario. People ignore storm warnings until the precipitation starts falling, then suddenly everyone rushes out at once. The roads become congested with anxious drivers, accidents spike, and stores run out of essentials just when people need them most. But here's what really gets meteorologists worked up about this pattern. Modern weather forecasting has become incredibly accurate, especially for major winter storms.

Even though the evidence is still early, this could be a very significant event in 2026 and lingering into 2027. Its function in the global earth system is to release heat from the deeper oceans that has been temporarily stored there. El Nino allows that subducted heat to be unearthed.

If you've ever glanced at your phone's weather app to check the day's forecast or to help plan for an upcoming storm, you've probably run across a scenario where you see an outrageous forecast. It happened to me earlier this week when I noticed my app was predicting more than 13 inches of snow for the Charlotte, NC area. Not only would that be a historic storm, but it would also be fairly apocalyptic for an area where even an inch of snow is a rarity.

The shower activity is going to continue throughout the day, National Weather Service meteorologist Lamont Bain said. As it pertains to thunderstorm risk, there's probably a 10-to-15 percent chance. There is a lot of instability between the upper low pressure and the lower air. That upper low is going to spin out there and not move much, and that's why the rain showers are going to be scattered throughout the day and why the best chances for thunder are out over the ocean.

While cold-stunned iguanas fall from trees in Florida and videos circulate of frozen "exploding" trees in the Northeast, Southern California is working up a sweat. A midwinter heat wave has descended on much of the state and is expected to spike temperatures as much as 20 degrees above normal in the coming week. The summer-like heat is thanks to a ridge of high pressure lingering high in the atmosphere that extends through the San Francisco Bay Area and into the Pacific Northwest.

Our weather is set to stay unsettled for the next little while with more rain, showers and blustery conditions to come, Though it will turn milder as we head into the weekend with warmer than average temperatures for this time of year. As we head into next week then staying mild and quite breezy with further outbreaks of rain on both Monday and Tuesday,

LIVE RADAR: Track storms as they move through the Bay Area with Live Doppler 7 Take a look at the chart above -- we will give each storm a number with 1 being the lightest type of storm and 5 being the most severe. This way you'll know what to expect. Number 1 means a light storm with 1/2 an inch of rain or less and likely lasting a few hours or less. Number 2 is a moderate storm with 1/2 an inch to one inch of rain forecast and could include scattered power outages.
