On August 6, a tropical disturbance developed into a tropical storm, skipping the depression stage. It edged south until August 8. At that point, it turned to the west. It would continue in that general direction until it dissipated. Celeste intensified into a hurricane on August 10. It then left the Eastern Pacific Hurricane Center's area of responsibility and entered the central Pacific. Celeste continued intensifying and eventually peaked as a Category 4 hurricane on the Saffir-Simpson Hurricane Scale. Celeste's Category 4 winds and central pressure of 940 millibars (840 hPa) made it the most intense cyclone of the season. After that, Celeste steadily weakened. After turning north, it dissipated on August 22 due to wind shear.
