Overview
- Mexico’s SMN says Front 19 is stalled over the Yucatán and southeast, with very heavy rain of 75–150 mm focused on northern and eastern Chiapas and southern Tabasco on Tuesday and Wednesday.
- A strong “Norte” event continues with gusts of 70–90 km/h in the Isthmus and Gulf of Tehuantepec and 50–70 km/h along parts of the Gulf coast, driving seas of 2.5–3.5 meters and hazardous marine conditions.
- Frigid air brings hard freezes to high terrain, with lows down to −10°C in parts of Chihuahua and Durango and −5 to 0°C in other northern and central sierras.
- In the U.S., the NWS flags extreme cold in Alaska with temperatures near −40°F and dangerous wind chills, while New York faces a sharp cold snap near 14°F and gusts up to roughly 45 km/h; a separate front brings rain to South Florida before a cooler, drier Tuesday.
- Conagua, SMN and civil-protection agencies maintain flood, wind, surf and cold-health alerts, advise caution near rivers and coasts, and keep shelters and updates active as the pattern holds through midweek.
