Derived winds

Today was my first real chance to glance at the Derived Winds.  They don't seem to be doing very good.

I plotted 1000 mb winds.

Looking along the LA coast SE of Cindy's center, we get a "red" wind that is from the 87 deg, 20 knots.  Winds should be from S/SW.  Also, "red" is supposed to be >= 50 knots.  Flag shows 20 knots.

"Yellow" flag is 58 deg, 42 knots.  Again direction should be S/SW.  Color is right this time, though.
