The 1943 Surprise hurricane was the first hurricane to be entered by a reconnaissance aircraft. The first tracked tropical cyclone of the 1943 Atlantic hurricane season, this system developed as a tropical storm while situated over the northeastern Gulf of Mexico on July 25. The storm gradually strengthened while tracking westward and reached hurricane status late on July 26. Thereafter, the hurricane curved slightly west-northwestward and continued intensifying. Early on July 27, it became a Category 2 hurricane on the modern-day Saffir–Simpson hurricane wind scale and peaked with winds of 105 mph (165 km/h). The system maintained this intensity until landfall on the Bolivar Peninsula in Texas late on July 27. After moving inland, the storm initially weakened rapidly, but remained a tropical cyclone until dissipating over north-central Texas on July 29.
