was the 1943 Mazatlan Hurricane, which made landfall as a Category 3 hurricane and caused $56 million (1971 USD; $ USD) in damage. Hurricane Bridget's storm surge caused flooding in the bay and damaged waterfront and beach facilities. Rough weather and violent seas also sank 20 boats plus a flagship of the Mexican Navy. Hurricane Carlotta On July 1 an area of weather developed about east of Clipperton Island. On July 2 the area of thunderstorms strengthened into Tropical Storm Carlotta. An Air Force reconnaissance aircraft flew into Carlotta on July 4 and found a system with a well-defined eye and good outflow, but winds only supported a tropical storm. Another reconnaissance plane found winds that were near hurricane strength on July 4. In post-season analysis, it was discovered that Carlotta was a hurricane for 24 hours on July 3 and 4. Later that day, Carlotta started weakening after moving into a less favorable environment. The storm continued to weaken until dissipating on July 8. Carlotta stayed over open waters during its entire life and no land was affected. Hurricane Denise On July 2 an area of weather got better organized about east of then Tropical Storm Carlotta. On July 4 satellite imagery indicated that the system had strengthened into Tropical Storm Denise and later into Hurricane Denise on July 6. The system continued to move west and on July 7, U.S. Air Force weather reconnaissance plane found a more organized system with sustained winds estimated to be with a minimum central pressure of 963 mbar (hPa; 28.4 inHg). By July 8, the system had sustained one-minute winds of and a minimum central pressure of . Denise reached a peak intensity of , a Category 4 on the Saffir-Simpson Hurricane Scale early on July 9, but then started to weaken. Denise had started a northwest movement towards Hawaii. A reconnaissance aircraft found surface winds of approximately 115 mph (185 mph) on July 9. Soon after, the eyewall started to dissipate, most likely because of cooler inflow. Over the next 48 hours, the system continued to weaken into a tropical storm. On July 13 the system was approaching the Hawaiian Islands, but a reconnaissance flight only found winds that were barely tropical storm strength. What was left of the storm quickly weakened and Denise became a remnant low. The remnants of Denise moved south of the Hawaiian Islands, but still brought
