Frequently asked

Are there any PIREPs near MA74?

39 pilot reports were filed within 100 NM of Larson's in the current reporting window, 29 of them reporting turbulence or icing.

What is a PIREP?

A pilot report is a first-hand account of conditions aloft filed by a pilot in flight: turbulence, icing, cloud bases and tops, flight visibility, wind and temperature. It is the only weather source that reports what an aircraft actually experienced rather than what a model or a ground sensor inferred. UA marks a routine report; UUA marks an urgent one.

How current are these reports?

The national PIREP feed carries roughly the last 90 minutes of reports and is republished every 5 minutes. A report is a snapshot of one aircraft at one place and time — conditions a few thousand feet away or twenty minutes later can differ.
