March 21, 2023, 2 p.m.

As another atmospheric river of rain and high winds makes its way into the Bay Area, campus is currently open and fully operational. Highway 17, south of Scotts Valley, is currently closed in both directions because of a downed tree, which may impede commuters from the Santa Cruz area. Additionally, downed trees have closed State Route 1 between Dolan and Moss Landing Road, which is impacting access to the Moss Landing Marine Laboratory facilities. Those impacted will receive direct contact from MLML leadership.

Additionally, there are road closures reported on Southbound Highway 84 near Pleaanton and Highway 82 in Burlingame is closed.

March 17, 2023: 4:13 p.m.

The Salinas River is forecasted to crest again at 25.7 ft Friday afternoon and then is expected to recede through the middle of next week. We are forecasted to get another round of rain, with an increasing chance of rain Sunday through Wednesday with rain totals around half an inch for that time frame.  This could affect the river levels.

Hwy 1 between Salinas Rd and Hwy 129 (Riverside Dr in Watsonville) remains open to traffic in both directions, allowing employees and students north of Moss Landing Marine Laboratory to commute to the facility.

Monterey County Emergency Services Evacuation Warnings in several areas north of Moss Landing have been lifted. However, the zones in which MLML resides (B-056, B-060 - all of our properties included) are still under an Evacuation Warning.

MLML will re-open Monday, but those who need to access the facility need  to remain vigilant of roads with standing water, trees falling and road closures.

March 13, 2023, 7:50 p.m.

We are monitoring the Monterey County evacuation declarations and maps as well as the NWS river gauges. The Salinas River currently is showing moderate flooding and it is projected to move to "major" flooding thresholds. MLML will be closed again on Tuesday for students, faculty and staff. Only essential personnel should be on site.

Additionally, employees and students coming to the main campus from Santa Cruz and Monterey Counties should pay close attention to road conditions and communicate with supervisors or faculty if unable to report to work or class.

March 12, 2023, 6:40 p.m.

An evacuation warning has been issued for the Moss Landing area because of flooding risk of the Salinas River. The MLML facility will be closed on Monday and we will provide further updates.

March 12, 2023, 12:35 p.m.

Of particular concern at this moment is the breach of the levee in Pajaro, which has inundated that community and cut off routes in and out of the area. This situation may impact normal operations at the Moss Landing Marine Laboratory (MLML). As of Sunday afternoon, both Highway 1 and Highway 152 are experiencing closures, making it difficult for students, staff and faculty to reach MLML. At this moment, long detours would be necessary to get there. Everyone who lives south of MLML should plan to work remotely on Monday. We want everyone to stay safe.

We also continue to monitor the status of the Salinas River, which could pose more problems in the Monterey Peninsula area should flooding occur. We will advise of any possible evacuation orders as well as road closures north of MLML over the next few days.

March 9, 2023, 1:45 p.m.
Rain and gusty winds expected on Thursday and Friday. Campus is expected to be open and fully operational.
