WeatherWeslaco Explores Stormwater Reuse to Strengthen Future Water Supply
Weslaco is investigating stormwater reuse as a means to enhance its water supply for agriculture, industry, and municipal needs. Mayor Adrian Gonzalez highlighted the city's efforts to convert stormwater from a flooding issue into a valuable resource. The city currently has facilities capable of storing about 288.7 million gallons of water. Collaborating with Hidalgo County and regional partners, Weslaco aims to retain stormwater instead of allowing it to flow away. This initiative is part of a broader strategy to ensure reliable water supplies for future economic growth and to improve flood management while supporting infrastructure development.

WeatherSolar Eclipse, Six-Planet Parade and Perseids Converge on Aug. 12
On August 12, 2026, skywatchers will witness a rare convergence of astronomical events, including a total solar eclipse, a six-planet parade, and the Perseid meteor shower. Before dawn, Jupiter, Mercury, Mars, Uranus, Saturn, and Neptune will align in the morning sky, with some visible without telescopes. Later that day, a total solar eclipse will occur, although the path of totality will not cross Texas. The eclipse will be visible in parts of Europe, with totality lasting under two and a half minutes in select areas. The night will conclude with the Perseid meteor shower peaking, offering ideal viewing conditions due to the new moon phase.
WeatherPlenty of sunshine and a parade of planets

WeatherLook to the Sky Tonight: The Perseid Meteor Shower Reaches Its Peak
One of the brightest and most popular meteor showers of the year peaks this week, providing an opportunity to see shooting stars streak across a particularly dark sky thanks to the new moon. The Perseid meteor shower has been active since mid-July, but it is expected to reach its peak during the night from Wednesday to Thursday. As the illuminated side of the Moon is currently facing the Sun and its night side looks toward Earth, moonlight will not interfere with one of the most anticipated skywatching events of the summer. Fortunately, the peak of the Perseids coincides with what may be the most awaited celestial event of the season: a total solar eclipse that will be visible from Spain, a small part of Portugal, Greenland, Iceland, and northern Russia on Wednesday.
WeatherThe solar eclipse crosses the sky this Wednesday: Where can you see it in the U.S.?
A solar eclipse will occur this Wednesday, with total visibility in parts of Spain and Iceland, while the U.S. will see a partial eclipse. The path of totality will start near the North Pole and move south through Greenland, Iceland, Spain, and Portugal. In the U.S., cities like Bangor, Portland, Boston, New York, Philadelphia, and Washington, D.C. will experience varying degrees of coverage, with the maximum in Bangor at 24%. NASA will stream the event live starting at 1:15 p.m. ET. The next total solar eclipse in the U.S. will be in August 2044.

WeatherExtreme summer heat causing severe vehicle damage, Edinburg mechanic warns
Extreme summer temperatures in the Rio Grande Valley are causing significant vehicle issues, warns Edinburg mechanic Joangel Velasquez. He experienced problems with his 2016 Chevy Malibu, including overheating and air conditioning failures. Joe Garcia, owner of Joe's Master Service Center, advises drivers to check their vehicles regularly, as heat can lead to battery failures and tire issues. He estimates that 35% of vehicles brought to his shop this year were already in poor condition. Garcia recommends visiting a mechanic for a thorough inspection during oil changes to prevent breakdowns. Velasquez emphasizes the importance of vehicle maintenance despite rising costs.
WeatherWeslaco Expands Flood Control Network Through Retention Facilities
Weslaco is enhancing its flood control measures by expanding its network of retention and detention facilities, according to Mayor Adrian Gonzalez. The city is investing in engineered structures, known as RDFs, to capture stormwater before it impacts homes. A key project involves converting Pablo Peña Park into a dual-purpose facility that serves as a park and flood protection. Since 2018, Weslaco has completed seven major detention projects, increasing stormwater storage capacity significantly. The mayor noted that flooding incidents have decreased from 2,500 homes affected in 2018 to just a few in recent storms, emphasizing the importance of regional cooperation in flood management.
WeatherMonitoring Tropical Waves with Development Potential in the Atlantic
PUERTO RICO – The National Weather Service (NWS) reported that they are monitoring a system with a 70% chance of development over the next seven days. The system is expected to become a tropical depression by the end of this week and move westward in the Atlantic. Meteorologist Zamira Mendoza previously indicated that it could pass northeast of Puerto Rico between August 15 and 17. 'This wave is anticipated to be over the waters of the Atlantic by tomorrow, Tuesday, and we could have a tropical depression or a tropical storm by the end of this week,' she explained. The NWS communicated that it is too early to determine what impacts, if any, it could have on the island.
WeatherMonitoring Tropical Waves with Development Potential in the Atlantic
PUERTO RICO – Invest 92L continues to gain organization in the Atlantic and has increased its chances of cyclonic development, becoming a system of interest for Puerto Rico as sectors of the island face drought conditions and rationing. The system, associated with a tropical wave located about 700 miles southwest of the Cape Verde Islands, is showing signs of increased organization with rain and thunderstorms. According to the latest report, the probability of formation has risen to 60% over the next 48 hours and to 80% over the next seven days. If the trend continues, a tropical depression could form in a couple of days as the system moves west and west-northwest through the central tropical Atlantic. Meanwhile, two other systems are under surveillance in the Atlantic basin. Invest 93L, located in the central subtropical Atlantic, maintains a 40% chance of development both in 48 hours and over the next seven days. A short-lived depression or tropical storm could form before the system reaches cooler waters, which would limit its development. Additionally, a tropical wave that just emerged from the western coast of Africa has a formation probability of 10% in 48 hours and 20% over the next seven days as it moves west or west-northwest.
