NASHVILLE (AP) - Tennessee health care volunteers are being flooded with a last-minute surge of consumers hoping to sign up for health coverage by deadline.

For many, Monday was a day of waiting and frustration because the federal government's website for choosing a health plan ground to a halt as people seeking coverage on the last day created heavy demand.

Federal officials set a deadline of March 31 to get health insurance but have said that anyone who started the process but was not able to get enrolled because of technical glitches will have a little extra time.

Federal figures show that between Oct. 1 and March 1, 77,867 Tennesseans enrolled in insurance through healthcare.gov.
