Severe Weather Action Checklists
Information for Students
Before A Severe Weather Event
- Residence Hall Room: Ensure residence hall room and suite windows are securely closed and latched before storms, especially during wind-driven rainstorms. Check that any balcony and courtyard drains near your room are free of visible debris. If not, contact F&M as soon as possible to report the issue.
- Report Maintenance Issues Early: Report any window seal leaks, roof drips, or standing water outside residence hall entrances immediately via the F&M Work Order portal, by calling Ext. 74559, or by emailing facilities@hmc.edu.
- Build a Personal Emergency Kit: Keep essential supplies easily accessible in your room in a bag you can grab in a hurry, if necessary:
- Portable USB power bank (fully charged) with cords for your cell phone, laptop and any other critical devices.
- Flashlights or LED portable lights or headlamps (No candles and open flames as these are fire risks.)
- 3-day supply of personal medications
- Bottle of water and protein bars; the College maintains supplies of drinking water and food for several days in the event of an emergency.
- Sturdy, closed-toe footwear and rain gear
- Commuter Planning: Any students commuting to and from campus should monitor traffic along Foothill Blvd (Hwy 111), I-210, I-10, and/or check the Metrolink San Bernardino Line status before leaving for campus. Coordinate with your professors in advance if severe weather impacts your route and check your email, watch for Mudd Alerts, and check the College’s homepage for last-minute announcements on class cancellations and closures. Prioritize your personal safety.
During A Severe Weather Event
- Check your HMC email and monitor Mudd Alert for official campus operational updates.
- Never attempt to walk or drive through flowing water or flooded intersections (e.g., Foothill Blvd (Hwy 111) or any low-lying local 5C streets).
- Avoid standing near tall eucalyptus trees or temporary structures during high winds or lightning.
Information for Faculty
Before A Severe Weather Event
- Establish Communication Plan: Review how you will contact students in your courses (via Canvas, email, or GoogleChat) if severe weather or local power outages affect access to campus or to classrooms.
- Flexible Attendance Expectations: Recognize that students who may be commuting or those who are cross-registered from the other 5C campuses may face varying weather and travel conditions getting to campus from their home campuses or from San Bernardino, Los Angeles, or other surrounding counties.
- Prepare for Hybrid/Remote Delivery: Review plans for how you would pivot to deliver your course remotely in case emergency campus-wide remote instruction is authorized by the Dean of Faculty.
During A Severe Weather Event
- Monitor official notices sent via Mudd Alerts as well as those from the Office of the Dean of Faculty and Emergency Preparedness and Safety.
- Direct any students who are in distress or who are experiencing housing issues to the Division of Student Affairs and the Dean on Call by calling Campus Safety at Ext. 72000 or emailing (dean_of_students@hmc.edu).
- Direct any faculty member who may be in distress to the Office of Human Resources or to the wellness resources available to all employees.
- Please contact your department chair directly to request and coordinate any temporary adjustments to your teaching schedule that may be needed.
Information for Makerspace, Shops, Labs and Clinic Spaces
Before A Severe Weather Event
- Critical Equipment:
- Verify that Uninterruptible Power Supply (UPS) units for critical computers, printers, servers, lasers, and analytical equipment are functioning properly and are appropriate for the type of equipment they are serving.
- Identify non-essential high-voltage or sensitive lab equipment that should be safely powered down ahead of forecasted windstorms or heavy lightning.
- Please review the HMC Laboratory Ventilation Management Program information. Verify that hazardous chemicals in the fume hood are sealed and secure.Ensure that all electrical equipment and cords are elevated at least six inches off the floor to prevent any damage or short circuits during potential flood events.
- Chemical and Specimen Security
- Ensure chemical storage cabinets and flammable storage units are properly latched.
- Move chemical containers, biohazards and sensitive samples away from windows and off floor levels prone to water seepage/flooding.
- Clinic, Shop and Makerspace Projects:
- Secure or relocate any outdoor Clinic project prototypes, testing rigs, or materials located in open courtyards or shop loading docks or in other areas prone to potential flooding or water intrusion.
- Please review the appropriate departmental and laboratory safety manuals and chemical hygiene information prior to any weather event.
- Contact F&M for details on the availability of emergency generators if needed.
Information for Staff and Supervisors
Before A Severe Weather Event
- Departmental Continuity: Review key operational tasks with your team and confirm who is designated as essential personnel for on-campus response (e.g., Facilities, Dining Services).
- Remote Work Preparedness: Ensure laptops, power cords, and key files are accessible if remote work is approved due to local flooding or travel hazards.
- Building Checks: Close all office windows, turn off electronics, and ensure ground-level office items are raised off the floor in areas prone to water intrusion.
During A Severe Weather Event
- Monitor your email as well as official notices sent via Mudd Alerts and those from Emergency Preparedness and Safety.
- Direct any staff member who may be in distress to the Office of Human Resources or to the wellness resources available to all employees.
- Direct any students who are in distress or who are experiencing housing issues to the Division of Student Affairs and the Dean on Call by calling Campus Safety at Ext. 72000 or emailing (dean_of_students@hmc.edu).
The Claremont Colleges
Because Harvey Mudd College is a member of the consortium, severe weather events require cross-campus awareness and collaboration:
- Cross-Registered Classes: If Harvey Mudd modifies class schedules or switches to remote instruction, the College will coordinate directly with cross-registered institutions (Pomona, Claremont McKenna, Scripps, Pitzer) via the Dean of Faculty regarding their operational status, as individual colleges may make independent operational decisions. Faculty should also keep in mind that students from other campuses may be facing different impacts from severe weather events (i.e., issues with their specific residence hall on their home campus, etc.) and may need greater flexibility during severe weather events.
- Consortium Services Continuity:
- Hoch-Shanahan Dining Commons: F&M and Dining Services prioritize continuous food service operations at Hoch-Shanahan during power outages and other disruptions.
- Honnold-Mudd Library, Student Health Services, and other shared services: Any operational adjustments regarding access to shared 5C/7C resources will be communicated via The Claremont Colleges Services (TCCS) announcements and via HMC emergency channels (Mudd Alerts, emails) as needed.
- Inter-Campus Pedestrian Paths: Use caution on shared 7C sidewalks and footpaths. Avoid walking near heavy tree canopies during strong wind gusts and avoid walking under large trees during any lightning events. Report any fallen limbs blocking pathways to Campus Safety (909.607.2000) as soon as it is safe for you to do so.
