Transportation officials recommended travelers on the east side of the collapse use U.S. Highway 95 in Arizona to get to the other freeways, and that in California drivers use state routes 86 and 111 to get to Interstate 8 into Arizona. The city also was expected to get a late repeat of Saturday's scattered showers and occasional downpours as remnants of tropical storm Dolores brought warm, muggy conditions northward. [...] Saturday's 0.36 inch of rain in downtown Los Angeles exceeded the 0.24 inch recorded July 14, 1886, which had been the wettest July day in nearly 130 years. Saturday's storm brought flash floods and power outages and turned Los Angeles County's typically packed coast into empty stretches of sand when the threat of lightning forced authorities to close 70 miles of beaches. The Los Angeles County Department of Public Health recommends people avoid swimming within 100 yards of a storm drain for 72 hours after heavy rain.
