Aside, but I want to call out Miami Dade Public Schools for being the only public school system I'm aware of that has had a contingency plan in place for years:
On rare occasions it may be necessary to close a school(s) due to weather or other emergency situations. If this occurs, the district will make every effort to ensure that our students' educational opportunities continue while at home. Throughout the years, the district has compiled a comprehensive collection of online content and digital resources. The district also provides mobile devices for students to check out for home use to ensure that district students (non charter) can continue their learning without interruption.
...
The Instructional Continuity Plan (ICP) has three components: Content Delivery, Mobile Devices, and Internet Access. Content Delivery explains which resources students will use for core instruction and which materials can be used as supplemental resources to enhance core instruction. Mobile Devices provides the steps the district is taking to ensure that any student who needs a mobile device to access the instructional resources will be provided with one, upon request, for the duration of the schools' closure. ... Internet Access poses the greatest challenge to ensuring that M-DCPS students can continue their studies while at home. The district has taken steps throughout the years to assist students in getting access to the internet at home through projects such as The 1Million Project; however, partnerships with service providers is crucial to providing free or reduced-cost internet service to students should the district close in case of emergency situations.

Also:
Miami-Dade County Public Schools (M-DCPS) is continuing its efforts to provide support to students and their families during school closures, which begin tomorrow, March 16. From distance learning, to community feedings, to facilitating childcare for essential medical personnel, M-DCPS stands firm in its commitment to support the South Florida community during this time of uncertainty.
A support hotline was established for teachers, students, and parents seeking assistance with distance learning.
During school closures, students and families may pick up hot meals to go, both breakfast and lunch, between 9:00 a.m. and 12:30 p.m.
A Mental Health Services hotline will be available for students.
An Employee Assistance Program hotline will also be available.

In contrast, I am extremely disappointed in how haphazard things are going in NC. I'm particularly disappointed in the UNC system which appears to have done zero advanced planning.
