Tropical Storm Dalila Rainfall Map Shows Where Mexico Might Get Hit Hardest
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Tropical Storm Dalila is expected to drop up to 9 inches of rain along Mexico's southwestern coast through Sunday morning, with National Hurricane Center (NHC) experts warning of mudslides and flooding. Newsweek reached out to the NHC by email for comment. Why It Matters The Eastern Pacific hurricane season began on May 15 and has seen a very active start. Tropical Storm Alvin kicked off the season in late May, followed by Hurricane Barbara and Tropical Storm Cosme. All three storms formed before the average first date of June 10 for a named storm in the region. Now, the fourth storm, Tropical Storm Dalila, is strengthening off the southwestern coast of Mexico. A map from the National Hurricane Center shows possible rainfall amounts in Mexico this weekend. A map from the National Hurricane Center shows possible rainfall amounts in Mexico this weekend. National Hurricane Center What To Know Maximum sustained winds have reached 40 mph, and forecasters anticipate that the storm will continue strengthening into Saturday. The NHC anticipates that Dalila will take a western trek away from land and further into the Pacific Ocean. However, the storm is close enough to southwestern Mexico that some indirect land impacts are anticipated. One of the biggest will be heavy rain. A rainfall forecast map published by the NHC shows that the heaviest rain is expected in coastal regions of Guerrero and Michoacan De Ocampo. "Rainfall totals of 3 to 6 inches are expected across portions of the Mexican states of Guerrero, Michoacán, and Colima through Sunday morning, with localized amounts up to 9 inches near the coast," NHC said in the forecast. "This rainfall will lead to areas of flooding and mudslides, especially in areas of steep terrain near the coast." In addition to heavy rainfall, the storm is causing high swells in the Pacific Ocean that will affect parts of the southwestern Mexico coast over the weekend. "These swells are likely to cause life-threatening surf and rip current conditions," a forecast from the NHC said. What People Are Saying An NHC forecast: "A turn toward the northwest is expected later today, with a turn toward the west forecast by Sunday. On the forecast track, Dalila is forecast to move parallel to, but offshore of, the southwestern coast of Mexico. "Dalila is a large system. Tropical-storm-force winds extend outward up to 310 miles (500 km) from the center." AccuWeather Senior Meteorologist Dan Pydynowski, in a report: "Beyond Dalila, another area could develop between June 17 and 20. This area of concern would be farther to the east, likely just offshore of the far southern coast of Mexico or even just offshore of Guatemala, but would likely take a similar track." What Happens Next Tropical Storm Dalila is expected to begin weakening later this weekend. Forecasts anticipate that it will be a post-tropical depression by Monday.

New tropical storm forms in Pacific as Atlantic basin remains dormant
AccuWeather's Enhanced RealVue™ Satellite of Tropical Depression 4-E south of Mexico on Friday afternoon. (AccuWeather) The eastern Pacific Ocean has spawned a new tropical storm, Dalila, which will swipe southern Mexico with flooding downpours and gusty winds. Meanwhile, the Atlantic basin remains dormant for now, but AccuWeather hurricane experts say it may spring to life during the second half of the month. The East Pacific is quickly gaining momentum following a slow start to the season, which officially began on May 15. Four storms have been named since May 28 -- Alvin, Barbara, Cosme and now Dalila. Dalila, which AccuWeather identified as a tropical rainstorm ahead of all other known sources on Thursday, was designated Tropical Depression 4-E by the National Hurricane Center on Friday morning before quickly being upgraded to a tropical storm. "Rain and wind from Dalila is likely to skirt the western coast of Mexico through this weekend before the storm moves westward into the open waters of the Pacific," AccuWeather Senior Meteorologist Dan Pydynowski said. Most of the wind associated with the tropical storm will stay offshore, but gusts can occasionally reach 40-60 mph along the immediate southern coastline of Mexico. The most significant impact in the region will be in the form of rain, with a swath of 2-4 inches expected with an AccuWeather Local StormMax™ of 8 inches. Flooding and mudslides can occur, especially since this zone recently got hit with tropical downpours from Barbara. Due to flooding rain and gusty winds, Tropical Storm Dalila is rated less than one on the AccuWeather RealImpact™ Scale for Hurricanes in Mexico. "Beyond Dalila, another area could develop between June 17 and 20. This area of concern would be farther to the east, likely just offshore of the far southern coast of Mexico or even just offshore of Guatemala, but would likely take a similar track," Pydynowski said. When will the Atlantic basin spring to life? Copious amounts of wind shear and dry, dusty air from the Sahara Desert have put a lid on tropical development in the Atlantic Ocean since the start of the basin's hurricane season on June 1. "There are some signs that tropical development could occur later in the month, however, just east of the Yucatan Peninsula or in the Bay of Campeche, between June 17 and 21," Pydynowski said. Even if a tropical depression or storm does not organize, tropical downpours are expected to frequent portions of Central America and southeastern Mexico into late June, which can enhance the risk of flooding and mudslides. "Any potential tropical depression or storm would likely be short-lived and remain mainly south of the United States, but some of its tropical moisture could be drawn northward into South Texas, even if there is no organized tropical development," Pydynowski said. AccuWeather is expecting a near- to above-historical-average Atlantic tropical storm and hurricane season for 2025. Between three and six named tropical cyclones are forecast to directly impact the U.S.

Hurricane Season Update: Storm Alvin Could Form Wednesday
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The first storm of the 2025 Eastern Pacific hurricane season could form as early as Wednesday, according to the National Hurricane Center (NHC), which reports that a low-pressure system south of Mexico is likely to develop into a tropical depression or tropical storm, Alvin. Why It Matters The 2024 hurricane season resulted in substantial losses, with storms impacting the Gulf and Caribbean regions. Major storms like Hurricane Beryl struck the Caribbean and Mexico, and later storms, including Hurricane Helene and Hurricane Milton, caused fatalities and economic losses estimated at $78.7 billion and $34.3 billion, respectively, according to the BBC, citing National Oceanic and Atmospheric Administration data. What To Know "Environmental conditions remain favorable for further development, and a tropical depression or tropical storm is expected to form later today or tonight as the low moves generally west-northwestward at around 10 [miles per hour]," the NHC said in a Wednesday morning update. The tropical rainstorm is expected to continue developing today, potentially reaching tropical depression or tropical storm status as it moves northwest. As it tracks farther over the Pacific later this week, it may intensify into a hurricane, forecasters at AccuWeather said. A forecast map from AccuWeather shows the system's expected path. A forecast map from AccuWeather shows the system's expected path. AccuWeather However, by the weekend, the system is likely to weaken as it approaches Mexico, encountering cooler waters and stronger wind shear. Despite this, it could still deliver locally heavy rainfall and gusty winds along parts of Mexico's west-central coast from late week into the weekend, according to AccuWeather. A tropical depression is a tropical cyclone with maximum sustained surface winds of 38 mph or less, according to the NHC. In contrast, a tropical storm features sustained winds ranging from 39 to 73 mph. The Eastern Pacific hurricane season began on May 15. It runs through November 30. What People Are Saying Fox Weather meteorologist Britta Merwin said: "That's usually how things work for the [Eastern Pacific]. You know, our water temperatures cool significantly off of Baja. This will generally be indirect impacts because, although this is tracking towards Baja and also the Pacific coast of Mexico, it will no longer be a tropical system at that point because the water temperature is significantly cooler." AccuWeather meteorologist Dan Pydynowski told Newsweek: "Both the Atlantic and East Pacific name lists rotate every 6 years. Storms with major land impacts are 'retired.' A meeting every year of the World Meteorological Organization (WMO) determines which names from the previous year should be retired. Storm list names are maintained and updated by the WMO." What Happens Next AccuWeather meteorologists are forecasting 14 to 18 tropical storms and seven to 10 hurricanes in the eastern Pacific for 2025. In comparison, the historical averages are 15 tropical storms and four hurricanes.

Eyes on the southwest Atlantic for early-June tropical development
Soon after the likely formation of the first tropical storm in the eastern Pacific basin, there will be some opportunities for tropical development in the Atlantic, perhaps close to Florida, Central America and Mexico, during the first couple of weeks of June, AccuWeather meteorologists say. June 1 marks the official start of the Atlantic hurricane season. Early-season tropical storm formation often has many obstacles, including harsh winds (strong wind shear), dry air and cool water. As the season progresses, moist air, warmer waters and lessening wind shear make it easier for tropical storms to form. AccuWeather meteorologists look for atmospheric patterns that can help jump-start tropical development early in the season, when conditions are typically less favorable. The Central America gyre is a large, slowly spinning area of low pressure that usually forms over Central America and can sometimes give birth to early-season storms. This failed to form in early May, which is why no tropical storms formed during that time. Another setup that can aid early-season development is a lingering front in the Gulf, the Caribbean, or the southwest Atlantic. When a front stalls, it can create enough moisture and upward motion in the atmosphere to gradually support tropical formation. "We will be watching a zone stretching from Florida waters to the Bahamas and Cuba during the first few days of June," AccuWeather Senior Meteorologist Dan Pydynowski said. This area will produce a broad region of showers and thunderstorms, which may help ease dry conditions over the Florida Peninsula. Any tropical development in this zone during the first few days of June is unlikely, but that could change if some slight spin develops in the region. •Have the app? Unlock AccuWeather Alerts™ with Premium+ Just a few days later, over the western and central Caribbean, the combination of that lingering front, congregating moisture, and perhaps a tropical wave could assist in stirring up some tropical trouble, Pydnowski explained. A tropical wave is a ripple of low pressure that often contains showers and thunderstorms and travels from east to west across the tropical Atlantic and Pacific. Pydnowski noted that any potential development is still about 10 days out, and conditions that support tropical organization may not come together. Beyond a couple of tropical waves of low pressure moving westward, much of the tropical Atlantic appeared to be mostly free of cloud cover Tuesday. The areas near Central America, the Caribbean Islands, and the southeastern part of North America are the favored spots for early-season tropical development. AccuWeather's team of long-range forecasters, including lead hurricane expert Alex DaSilva, is expecting 13-18 named storms this season, with seven to 10 becoming hurricanes. Of these, three to six are forecast to have a direct impact on the United States. Want next-level safety, ad-free?
