Meteorological services continue to monitor several low-pressure zones in the Pacific and Atlantic oceans for potential cyclonic development. In the Pacific, the National Water Commission (Conagua) and the National Meteorological Service (SMN) are tracking two systems. One system, located systems that have seen increased development probabilities. A system south of the Jalisco, Colima, Michoacán, and Guerrero coasts, coasts now has a 70 90 percent probability of development and developing into a tropical cyclone within 48 hours. If it forms, it could become tropical the third active cyclone Iselle. in the region, joining Hurricane Karina and Tropical Storm Lowell. A second system west-southwest of the Baja California peninsula maintains a 50 percent probability of development. These conditions, influenced by the Mexican monsoon and tropical waves, conditions are expected to bring heavy rainfall, thunderstorms, and high waves to various Mexican states, with Sinaloa and Nayarit projected to receive the most intense precipitation between 75 and 150 millimeters. Additionally, precipitation. In Veracruz, Conagua reports that a heatwave is affecting northern Mexico, with temperatures in Baja California low-pressure channel and Sonora potentially exceeding 45 degrees Celsius. tropical wave 34 will bring heavy rains and thunderstorms to several river basins, including the Tonalá and Coatzacoalcos rivers. In the Atlantic, Atlantic and Gulf regions, surveillance remains active. In the region east-northeast of the Quintana Roo coast, authorities are tracking two systems: one northeast A low-pressure zone north of the Bahamas with Yucatán Peninsula has reached a 40 50 percent chance of development over seven days, and another off cyclonic development, prompting monitoring in Quintana Roo. In the coast Gulf of Africa with Mexico, meteorologists warn that a 70 percent chance of development within 48 hours tropical depression or storm, potentially named Edouard, may form near the Louisiana coast and seven days. move toward the Texas-Louisiana border, bringing heavy rainfall and potential flooding to Southeast Texas, including Houston. In the Dominican Republic, INDOMET is monitoring a low-pressure area south-southeast of continues to monitor weather patterns, while the Cape Verde islands with a 70 percent probability of becoming a cyclone within 48 hours and seven days. The country is also experiencing region remains subject to extreme heat, with heat sensations reaching up to 47 °C in Barahona and Santo Domingo. Variable weather, including scattered showers and wind gusts variable weather caused by a tropical wave waves and a trough, continues to affect the region. troughs.
