Through Atmospheric pressure and Earthquake

Brenda made two landfalls in Mexico: first in the Yucatan and later in Campeche. Little damage resulted from the storm throughout the Yucatan Peninsula. However, severe damage took place in areas near Brenda's second landfall. A total of 10 people were killed by the hurricane and over 2,000 more were left homeless. Flooding caused by Brenda was considered to be the worst in over 25 years in some places.

Meteorological history

Hurricane Brenda originated from a tropical wave that moved off the western coast of Africa on August 9; however, the initial wave quickly weakened upon entering the Atlantic Ocean. By August 13, the wave began to regenerate as it passed through the Lesser Antilles, producing scattered shower and thunderstorm activity. Several days later, convection associated with the system consolidated into a central, organized mass and on August 18, the system had become sufficiently organized to be declared a tropical depression. Early the next day, the depression strengthened into Tropical Storm Brenda following reports of gale-force winds from ships in the vicinity of the storm. Prior to its first landfall, Brenda suddenly intensified, with the central barometric pressure decreasing to 992 mbar (hPa; 29.29 inHg) and winds reached 65 mph (105 km/h). The storm moved inland roughly 30 mi (48 km) north of Cozumel at the northern edge of the Yucatan Peninsula on August 19.

Roughly 24 hours after landfall, the center of Brenda passed directly over the city of Mérida, Yucatán. By this time, a strong ridge over southern Texas and northern Mexico caused the storm to take an unusual southwest turn. Later on August 20, the center of Brenda moved into the Gulf of Mexico, specifically the Bay of Campeche. Once back over water, Brenda began to quickly intensify, attaining hurricane status later that day. The next day, a well-defined eye had developed and the storm attained its peak intensity as a high-end Category 1 hurricane with winds of 90 mph (140 km/h) and a minimum pressure of 977 mbar (hPa; 28.85 inHg). Around this time, the tropical storm force winds extended out 150 mi (240 km) to the north and 75 mi (121 km) to the south. The storm made landfall later that day near Ciudad del Carmen, Mexico at this intensity, becoming the first hurricane to strike the region on record. After moving inland, Brenda rapidly weakened to a depression by the morning of August 22 and dissipated later that day.
