OPM has authorized federal agencies to make excepted appointments on a temporary basis for up to one year in support of federal recovery efforts related to Hurricanes Irma and Harvey.
Those hired must be directly involved in recovery and relief efforts. The appointments may be extended for up to one year (two years total), and agencies must apply veterans’ preference rules when filling positions, and otherwise have procedures in place for acceptance of applications. Pass-over procedures also apply to these appointments. Here’s the announcement: https://www.chcoc.gov/content/emergency-hiring-situation-resulting-hurricane-harvey-and-hurricane-irma

OPM has also set up an emergency leave transfer program for federal employees impacted by the hurricanes. (Some 60,000 federal employees live in the Houston area, and roughly 90,000 live in Florida.)
