 After reaching the Gulf of Mexico, Hilda strengthened to reach peak winds of 125 mph (205 km / h) late on September 18. Before the hurricane moved ashore, there was residual flooding in Tampico from earlier Hurricane Gladys. Hilda struck the city early on September 19, with gusts estimated at 150 mph (240 km / h). It dropped heavy rainfall that flooded 90 % of Tampico, while its strong winds damaged half of the homes, leaving 15,000 homeless. The storm killed 300 people and caused over $ 120 million (1955 USD) in Mexico. Ongoing flooding caused an outbreak of dysentery, and about 10 days after Hilda struck, Hurricane Janet struck the same region and caused further flooding and damage. Collectively, the damage from the storms represented about half of Mexico's budget in 1955.
