Hurricane Stan was a rather weak but deadly
tropical cyclone that affected areas of Central America in early October 2005. The eighteenth
named storm and eleventh
hurricane of the
2005 Atlantic hurricane season, Stan formed from a
tropical wave on October 1 after it had moved into the western
Caribbean Sea. The depression slowly intensified, and reached
tropical storm intensity the following day, before subsequently making its first
landfall on the
Yucatán Peninsula. Traversing the peninsula, the tropical storm weakened, but was able to re-intensify once it entered the
Bay of Campeche. Under favorable conditions for
tropical development, Stan attained hurricane strength on October 4, and later reached peak intensity with winds of 80 mph (130 km/h) and a minimum
barometric pressure of 977
mbar (
hPa; 28.85
inHg). The hurricane maintained this intensity until landfall near Punta Roca Partida, Mexico later the same day. Once over the mountainous terrain of Mexico, however, Stan quickly weakened, and dissipated on October 5.
