Hurricane Edna was a deadly and destructive major hurricane that impacted the United States East Coast in September of the 1954 Atlantic hurricane season
1954 Atlantic hurricane season
The 1954 Atlantic hurricane season caused over $750 million in damage, the most of any season at the time. The season officially began on June 15, and nine days later the first named storm developed. Hurricane Alice developed in the Gulf of Mexico and moved inland along the Rio Grande,...

Meteorological history

Hurricane Edna originated in an easterly tropical wave

. A ship in the vicinity of the disturbance reported heavy squalls and wind gusts to 70 mph (112.7 km/h). Additionally, the island of Puerto Rico experienced torrential rainfall in association with the storm. Operationally, the system was not recognized to have organized into a tropical cyclone until September 6; it is listed in the Atlantic hurricane database as achieving tropical storm intensity early on September 4. Edna proceeded west-northwestward, bypassing Hispaniola

, approximately 20 mi (32.2 km) is diameter. The overall circulation increased in size as banding features became more well-defined. The storm reached its peak winds of 120 mph (193.1 km/h) and maintained them for over two days. However, reconnaissance data was at times inconsistent and inaccurate, leading to suspicious and unlikely jogs in the storm's track. The cause of these errors is attributed to misinterpretation of radar

Midday on September 9, while tracking nearly due north, Edna's minimum central barometric pressure fell to 968 mbar (28.6 inHg), but is believed to have leveled off shortly thereafter. The radius of hurricane-force winds increased, and the storm may have become asymmetrical, with convection concentrated to the right of the center, although this was not confirmed due to a lack of data.
