Tropical Storm Selma was the first tropical storm on record to make landfall in El Salvador, and only the second Pacific tropical cyclone to attain tropical storm strength east of 90°W, the other being Alma of 2008.[1] The twentieth tropical cyclone and eighteenth named storm of the 2017 Pacific hurricane season, Selma formed from a Central American gyre on October 27. The storm tracked northeastward and reached its peak intensity as a minimal tropical storm before making landfall east of San Salvador, El Salvador early on October 28. Selma rapidly weakened after making landfall, and its remnant circulation dissipated overland at 18:00 UTC on the same day.
In anticipation of the storm's arrival, tropical storm warnings and watches were issued for the coast of El Salvador and the Pacific coast of Guatemala. Heavy rainfall associated with the storm and a cold front resulted in flash-flooding and mudslides that caused minor damage in El Salvador. The storm also caused 17 fatalities in Honduras and Nicaragua, where heavy rainfall caused flooding and mudslides as 13 rivers topped their banks.
