1909 Monterrey hurricane

Impact

Caribbean

Prior to the hurricane's devastating impacts in Mexico, it brought heavy rains and high winds to several of the northern Caribbean Islands. The first to be affected by the storm were the Leeward Islands; however, no known damage resulted from its passage. Moderate rain and gusty winds were reported in Puerto Rico as well as the Dominican Republic and Jamaica. In eastern Jamaica, between Aquavale and Hope, the banana crop was largely destroyed. Haiti suffered severe damage reported in many towns, with homes destroyed and many homeless. Much of Cuba was also impacted by the storm, with winds up to 60 mph (95 km/h) being recorded as far north as Havana.

Mexico

Although a borderline Category 2–3 hurricane when it made landfall in the Yucatán Peninsula, little is known about the storm's impact in the region. The United Fruit Company steamship, Cartago, encountered adverse conditions in the hurricane while traversing the Yucatán Channel about 25 mi (40 km) offshore. Rocked by severe winds up to 100 mph (160 km/h) and swells for 12 hours, the ship suffered damage to its pilothouse, starboard deck, and railings. Aside from seasickness, none of the vessel's 24 crewmen were injured. However, following the hurricane's second landfall, the resulting damage was catastrophic. During the overnight hours between August 27 and 28, cities along the coastline of Tamaulipas likely sustained severe damage from the hurricane's storm surge and high winds. Newspaper reports stated winds reached 60 mph (97 km/h) in Veracruz and 75 to 90 mph (121 to 145 km/h) from Tampico to Matamoros in Tamaulipas.

The worst of the damage took place further inland, within the state of Nuevo León. There, torrential rainfall triggered a flood even exceeding 100-year flood values. According to meteorologists in Mexico, the storm dropped 17.5 in (440 mm) of rain over a 40‑hour span. Further rains fell for the following 32 hours, worsening the situation. Adobe homes that survived the initial onslaught collapsed in these rains, killing many people. The rising Santa Catarina River flowed into the San Juan River, causing an abrupt rise and subsequent overflow of water that caught residents off-guard. Multiple small communities were swept away in the ensuing floods.

According to Mexican officials, overnight on August 27, the reservoir dam near Nuevo León's capital city, Monterrey, burst, flooding more than half of the buildings in the city, as well as all of the nearby town of San Luisto. The normally 150 yd (140 m) wide river swelled to 0.75 mi (1.21 km) wide. Steel works and smelters situated along the Santa Catarina River were destroyed after the river rose well over its banks. Hundreds of homes were destroyed throughout the city, leaving an estimated 20,000 people homeless. According to the American Society of Civil Engineers, an enormous 235,000 ft³ (6,650 m³) of water was being moved per second during the height of the flood. The raging rivers finally subsided by August 30.

At the height of the floods, residents were forced to seek refuge on the roofs of two-story buildings; however, the Santa Catarina River was flowing at a very fast pace of 20 mph (32 km/h). The force of the current led to most homes being taken off their foundations and sent downstream, resulting in the deaths of anyone inside. In one incident, 90 people died after seeking refuge in a school after their homes collapsed. However, not long after entering the building, flood waters inundated the structure and caused it to collapse. By the morning, survivors reported that the state of the city was "indescribable".

The San Francisco church, built in 1572, was destroyed during the storm. Damage from the hurricane was estimated to have been at least $50 million (1909 USD; $1.79 billion 2026 USD). Of this, roughly $20 million was attributed to railroad losses. Throughout Mexico, reports indicated that about 4,000 people were killed as a result of the storm, making it one of the deadliest Atlantic hurricanes on record. Some estimates place the death toll as high as 5,000 and others as low as 3,000. Of these fatalities, 800 are believed to have been in the south side of Monterrey where four blocks of the city were completely destroyed.

United States

While the hurricane traversed Cuba on August 24, the United States National Weather Bureau issued hurricane warnings for southern Florida between Tampa and Jupiter and advised ships to avoid the eastern Gulf and South Atlantic. Ahead of the hurricane's landfall in Mexico, the Weather Bureau raised storm and hurricane warnings for the Texas coast on August 27. Upon landfall, the storm's northern half brought increased swells and gusty winds to, recorded up to 68 mph (109 km/h), to parts of southern Texas. Tides were described as the highest in several years. Tarpon Beach was devastated by surging waters, with every structure except the lighthouse and quarantine station being damaged or destroyed.

Debris from the town washed ashore 3 mi (4.8 km) away at Point Island. Rescued personnel from Brazos Santiago were able to save all of the stranded residents as waters rose. The coastlines of Mustang Island and San José Island straddling Aransas Pass were submerged. Low-lying areas north of Corpus Christi were inundated by 1 to 3 ft (0.30 to 0.91 m) of water and several piers were damaged. A tornado near Beeville destroyed a large barn and outhouse. Rainfall from the hurricane reached 7.8 in (200 mm) in Falfurrias between August 27 and 28. Twenty-four-hour rainfall reached 5.88 in (149 mm) in La Parra, a state record for the month of August at the time. Overall damage in the state was minimal from the storm and there were no deaths.

Aftermath

Crippled communication networks and infrastructure hampered relief efforts in the immediate aftermath. More than 60 mi (97 km) of railway was destroyed and numerous roads were washed out. The city of Monterrey was entirely cut-off and within days, food supplies were low and residents were at risk of famine. Local water supplies were rendered useless. Many residents and visitors in the city did all they could to help rescue those trapped in the flood waters and take care of the homeless. According to The New York Times, one person rescued 30 people stranded in flood waters. Numerous rescue operations were undertaken during the flood, saving many lives. However, survivors faced another issue after losing their homes: lack of food. Food was unavailable to most residents in the wake of the storm until August 31 when the first relief supplies arrived. Even then, most only received a small amount of bread and beans. Municipal authorities and the American Consulate provided bread, coffee, and soup to more than 10,000 people. Benefit performances and bull fights were planned to raise charity money. American Consulate General Hanna appealed for American aid on August 30 and the American Red Cross appealed for $20,000.

Once the flood along the Santa Catarina River receded, searches were conducted to attempt to locate the bodies of victims. However, reports indicated that the river bed was similar to quicksand and most bodies on it were likely underground. To deal with the large number of bodies in the wake of the disaster, Mexican officials decided to cremate and mass bury victims. By mid-September, between 1,600 and 1,800 people were hired to repair and rebuild the devastated railways in Nuevo León. In 2009, the third edition of the book El Río Fiera Bramaba: 1909 by Oswaldo Sánchez, re-accounting reports form people who experienced the flood, was planned. According to the director of publications at the Universidad Autónoma de Nuevo León, the book was considered one of historical quality. In memory of those who perished during the flood, the book was released to the public on August 27, 2009, the 100 year anniversary of the disaster.
