First image is the winds aloft at 850 mb (approx 5000 ft). Second image is a snapshot of the base velocity showing north to south directionality at a peak of 15 to 20 knots. Third image is an animated gif with snapshots every half hour of the base reflectivity above radar station RTX. Animation runs from around 8:00 pm pdst yesterday evening through 5:00 am pdst this morning. (Click on the thumbnails to view the full-sized images and animation.)
Sunset last night was at 8:43 pm pdst.

Light northerly winds along the coast probably wont push anything into the area but wont impede any migrants either.

Overall density is still rather light.
