 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 .
