Through The Maritimes and Landslide

The storm's slow track over Central America between June 5–8 led to copious rainfall and triggered deadly floods; El Salvador and Honduras suffered most among Central American countries. Rainfall totals exceeded 25 in (640 mm) in some areas. Fourteen rivers in El Salvador rose above their banks. Entire villages in El Salvador were destroyed by the floods, with damage extensive in the country's interior and along its Pacific coast. Communications with El Salvador were downed for 36 hours. Extensive damage to crops and infrastructure occurred in and around San Salvador, where at least 2,000 people may have perished; property damage totaled $2 million (1934 USD) in the city. The hurricane was especially deadly in Honduras, primarily west and north of Tegucigalpa. In Ocotepeque, torrential rainfall caused a landslide that formed a natural dam, allowing floodwater to accumulate behind it. The dam failed on June 7, and the resulting debris flow downstream destroyed most of Ocotepeque and killed an estimated 468 people. The Yucatán Peninsula's sparse population mitigated significant damage when the hurricane struck Quintana Roo on June 9, though crops were impacted between Progreso and Payo Obispo.

Much of the shores of the Gulf of Mexico were affected by the hurricane due to its erratic path. High winds and coastal floods stemming from swells generated by the storm reached Tamaulipas and Brazos Island along the western extents of Gulf of Mexico, while a stationary front tapped into moisture from the storm to produce heavy rainfall across southern Georgia and Florida. The worst of the hurricane's impacts associated with its landfall in Louisiana were caused by the storm's rainbands that raked across Louisiana and Mississippi ahead of the hurricane's center. Six people were killed in Louisiana and four were killed in Mississippi. Approximately 3,000–7,000 homes were damaged in Louisiana. The storm continued to produce high winds and flooding rainfall as it tracked northeast across the Mid-Atlantic states and into Canada, causing power outages and property damage.

Meteorological history

The circumstances leading to the storm's formation in the western Caribbean Sea were unclear, marked only by inclement weather in the Gulf of Honduras. An area of low pressure developed in the area and organized into a tropical depression by 12:00 UTC on June 4, strengthening into a tropical storm six hours later. The following day, the cyclone made landfall near Belize City in the British Honduras with maximum sustained winds of 50 mph (80 km/h). Over the next two days, the storm took a looping path primarily through Guatemala. Although interaction with land initially weakened the cyclone, the storm's winds quickly increased when it passed near Guatemala's Pacific coast. It re-entered the Gulf of Honduras on a northward path early on June 8 and strengthened into a hurricane by June 9. Concurrently, it curved towards the west, leading to a landfall along the Yucatán Peninsula on June 9 with winds of 80 mph (130 km/h).

The next day, the system moved into the Gulf of Mexico as a tropical storm on a northwestward heading. Two days later, the storm executed another loop, restrengthening into a hurricane before taking a northward course. Observations from ships in the vicinity of the hurricane were suggestive of an intensifying system. On June 14, the storm attained winds of 100 mph (160 km/h), ranking it as a Category 2 hurricane intensity on the modern Saffir–Simpson scale. It held this intensity for two days and made landfall along the coast of Louisiana near Jeanerette at 19:00 UTC on June 16. Upon landfall, the storm's barometric pressure was 966 mbar (hPa; 28.53 inHg). The hurricane weakened and accelerated towards the northeast after moving ashore, though the swampy terrain of coastal Louisiana curtailed the weakening process. The storm's winds decreased below hurricane strength on June 17 and fell further to tropical depression strength on June 18 as the system tracked across Mississippi and Tennessee. Its entanglement with an approaching cold front on June 18 signaled the storm's transition into an extratropical cyclone. The storm continued towards the northeastern United States and the Canadian Maritimes, tracking across Nova Scotia and the northern shores of the Gulf of St. Lawrence before it was last documented on June 21 over Labrador.
