Narrative:

I was transporting a patient to a local hospital in ZZZ when I encountered, inadvertent IMC conditions. Per company policy, I contacted approach control, advised them of my situation, declared an emergency, and requested radar vectors for an ILS approach. The controller was extremely helpful and the flight continued to the airport without any problems. The airport was VFR upon arrival, but the area west of the airport was certainly below VFR minimums. Prior to accepting the flight, I checked both the current and forecast WX for the area and felt that the flight could be made safely.

Original NASA ASRS Text

Title: A BK117 MEDEVAC PLT ENCOUNTERED IMC DURING A VFR FLT IN ZZZ'S AIRSPACE.

Narrative: I WAS TRANSPORTING A PATIENT TO A LCL HOSPITAL IN ZZZ WHEN I ENCOUNTERED, INADVERTENT IMC CONDITIONS. PER COMPANY POLICY, I CONTACTED APCH CTL, ADVISED THEM OF MY SIT, DECLARED AN EMER, AND REQUESTED RADAR VECTORS FOR AN ILS APCH. THE CTLR WAS EXTREMELY HELPFUL AND THE FLT CONTINUED TO THE ARPT WITHOUT ANY PROBS. THE ARPT WAS VFR UPON ARR, BUT THE AREA W OF THE ARPT WAS CERTAINLY BELOW VFR MINIMUMS. PRIOR TO ACCEPTING THE FLT, I CHKED BOTH THE CURRENT AND FORECAST WX FOR THE AREA AND FELT THAT THE FLT COULD BE MADE SAFELY.
