Before the squall

I was trying to get a few things done in the field this morning, when I looked up to see this beautiful rainbow over the ocean:

 

I took a few pictures, including the one below, with a Gray Whale "photo-bombing" the rainbow seascape.  (The spout is on the left side just below the horizon.)

 

The sky became very dark and I decided I should head back before getting soaked, but I took one more shot looking to the northwest from Bodega Head, with the waves rolling into Salmon Creek Beach. 

 

I made it back to the office just in time.  It started pouring rain a few minutes later.  I think we recorded ~0.35 inches of rain within ~20 minutes!
