Overview
- Mexican agencies warned on June 12 that Tropical Wave No. 6 interacting with a broad low over the Bay of Campeche will bring intense rains and storms to 19 states with forecast totals of 75–150 mm in Jalisco, Puebla, Veracruz, Oaxaca, Chiapas, Tabasco, Campeche, Yucatán and Quintana Roo.
- The U.S. National Hurricane Center gave the Bay of Campeche low about a 10 percent chance of tropical cyclone formation in the short term but said the system’s large moisture field will still produce heavy inland rainfall.
- Authorities cautioned that the expected downpours could trigger electrical storms, hail, rapid rises in rivers and streams, landslides in vulnerable terrain and urban flooding, and they urged people to follow Protección Civil and Conagua guidance.
- A separate severe convective outbreak in the Chicago area on June 11 produced winds above 70 mph, left more than 172,000 ComEd customers without power, forced dozens of flight cancellations and paused CTA service for hours.
- Forecasters also said an extreme heat wave will persist in northern Mexico with temperatures above 45°C in parts of Baja California and Sonora and that a following tropical wave this weekend could reinforce rainfall risks in the south and east.
