SCAN OVERVIEW:

 

0850 Z

Begin Microphysical Scanning, Switching to MicroNear135: Switching to 960 Hz PRF. Arturo driving MicroNear135 to capture initiation over the GOC.

 

0900Z, Base reflectivity

 

0930 Z

Line of strong cells right on the coastline 60-120 km NW of the radar.

 

0930Z, Base reflectivity

 

1007 Z

Shifted clock-wise a little bit to keep them in the sector.

 

1000Z, Base reflectivity

 

1030 Z

End Microphysical Scanning, Switching to ClimoNear: Storms are too spread out for sectors and the ones we are following up close have weakened considerably.

 

1030Z, Base reflectivity
