Editor's note: This updates with the Yosemite Valley reopening to the public on Tuesday, lodging and commercial services to resume operations Wednesday.
In the end, the forecast was wrong. While the Merced River did rise above flood stage as it rolled through the Yosemite Valley, predictions of a crest more than 8 feet above flood stage never materialized, leaving Yosemite National Park's main destination drenched but seemingly little worse for the storm.
After checking the valley for damage, park officials announced that the valley could reopen to the public on Tuesday at 8 a.m. but stressed that there would be limited services.
"There is no access to Yosemite Valley via the El Portal Road (Highway 140) due to a rockfall that occurred early this morning. There is no estimated day or time for the road to reopen. The Hetch Hetchy Road is also closed due to a rockfall," park spokesman Scott Gediman said in an email.
Overnight accommodations and commercial services in the Yosemite Valley were to resume on Wednesday, while campground operations would resume Tuesday night.
Early Monday morning the gauge on the Pohono Bridge on the west end of the valley showed the river had peaked at 12.7 feet before starting to drop. Weather forecasts leading into the wet weekend carried predictions that the Merced would crest at more than 18 feet, or 8 feet above flood stage. That never happened as the storm veered to the north.
According to Mr. Gediman, "(A)lthough there was no major flooding in Yosemite Valley, both roads and infrastructure (water systems, sewer systems, etc.) were impacted."
"Park visitors are asked to be aware of hazards, including potential wet and icy road conditions, rockfall, and debris in roadways," he added. "The park has experienced significant rainfall over the past month and ground saturation could lead to hazardous conditions along park roadways."
