Essential personnel should report to work, and employees scheduled to work remotely should do so. All employees should check in with their supervisors.\n\nDue to the campus closure, there will be no Inter-Campus Bus service or Ambler Train Station shuttle service on Friday, Sept. 3.\n\nThe university response to this severe weather incident has been both swift and supportive. University Operations as well as multiple tree and roof companies and restoration services have been on campus all day working tirelessly to ensure campus can open as soon as possible.\n\nPlease note that due to the current conditions on campus and ongoing clean-up, no one other than essential personnel is permitted on campus during the closure.\n\nThis has been an unprecedented event. If you need to speak to someone, we encourage you to reach out to Tuttleman Counseling Services.\n\nWe also encourage you to support the university s Student Emergency Aid Fund. The purpose of the fund is to provide short-term financial assistance during unusual or unforeseen circumstances such as now. If you are a student in need of emergency aid, please fill out the online application.\n\nUniversity employees can receive assistance through HR s Employee Assistance Program. Services are available to employees online 24/7 or contact 1-888-267-8126.\n\nWe will continue to provide ongoing updates as they become available.\n\nBest,\n\nVicki Lewis McGarvey \nVice Provost for University College\n\nBeth Shepard-Rabadam \nAssociate Director, Temple University Ambler",

  "context": "Temple University's Ambler Campus sits in suburban Montgomery County, Pennsylvania, north of Philadelphia. On the evening of September 1, 2021, the remnants of [Hurricane Ida spawned a tornado outbreak across the Northeast](https://en.wikipedia.org/wiki/Effects_of_Hurricane_Ida_in_the_Northeastern_United_States), and an EF2 tornado with winds near 130 mph passed directly through the center of the Ambler Campus at about 5:45 PM. A resident adviser herded students into a downstairs hallway, and [roughly two dozen students and staff were stranded overnight](https://temple-news.com/temples-ambler-campus-damaged-by-tornado/) when downed trees and power lines made the roads impassable. The [Philadelphia Inquirer reported tens of millions of dollars in damage](https://www.inquirer.com/education/temple-university-ambler-tornado-damage-ida-20210917.html), with all but two of the campus's buildings seriously damaged and more than 500 trees destroyed. Temple [closed the Ambler Campus and canceled in-person classes there on September 2 and 3](https://ambler.temple.edu/about/tornado-recovery-temple-university-ambler), while Main Campus in Philadelphia continued operating. The case illustrates the compressed timeline of a tornado emergency notification (a shelter alert must arrive minutes before impact) followed by a prolonged shelter-in-place driven by debris rather than continuing storm danger.",
  "keyFindings": [
    "A tornado warning leaves only minutes for an emergency notification to reach the campus before impact, unlike the hours of lead time a hurricane allows",
    "Shelter-in-place at Ambler extended overnight not because the tornado threat continued but because downed trees and power lines blocked every road off campus",
    "The same Hurricane Ida system that flooded New Jersey campuses produced the tornado that devastated Temple Ambler, showing one weather event generating very different campus emergencies",
    "No one on campus was killed or seriously injured despite an EF2 strike, a testament to the shelter response by resident advisers and students"
