maintained its status and eventually intensified into Tropical Storm Miriam around 00:00 UTC on August 27. Miriam turned west-southwest and entered the Central Pacific, where it intensified into a hurricane at 12:00 UTC on August 28 and reached peak winds of twelve hours later. Miriam then began to steadily weaken as it passed south of Hawaii, and the cyclone dissipated after 00:00 UTC on September 2. Hurricane Norman On August 29, a tropical wave and attendant disturbance were located southwest of Acapulco. The system organized into a tropical depression by 18:00 UTC on August 30, and it became Tropical Storm Norman six hours later. Norman moved west-northwest while gaining strength, intensifying into a hurricane around 06:00 UTC on September 1 and developing a small eye shortly thereafter. The hurricane rapidly intensified over warm waters, catapulting to Category 4 intensity by 06:00 UTC on September 2. Norman peaked with winds of twelve hours later, equaling Fico and Hector as the strongest storm of the 1978 season. A reconnaissance aircraft in the cyclone at this time observed a diameter eye. High pressure steering the storm west-northwest gave way to strong southwesterly flow aloft, causing the storm to recurve northeast in a much less favorable environment. Subsequent recon missions found a much weakened cyclone, and Norman ultimately dissipated south of San Clemente Island after 00:00 UTC on September 7. A man and his son were killed offshore Mexico after their boat crashed in rough seas. Along the coastline of California, waves up to caused damage to ships and prompted lifeguards to rescue hundreds of swimmers. The remnants of Norman combined with a trough and a front to produce accumulating precipitation across the Sierra Nevada and surrounding locales, including rainfall up to and snowfall up to . These rains caused numerous traffic accidents which resulted in the deaths of two people. Flooding also caused extensive damage to California crops. The raisin crop in particular was 95 percent destroyed, the biggest agricultural loss in California state history. Lingering cloud cover prevented ample drying in the wake of the storm, exacerbating agricultural losses, which were placed in excess of $300 million. In higher elevations, four people were killed after suffering from hypothermia. Sporadic power outages affected 15,000 customers. Hurricane Olivia The Atlantic's Hurricane Greta struck Central America and maintained its status as a tropical cyclone while crossing into the East Pacific. It emerged into the Gulf
