Question About NOAA API

In what format is the lat/long entered on the setup screen for the new NOAA API?

I entered what was on the NOAA map; but I must have it incorrect; as the forecast image showed the forecast for Kansas instead of Walnut Creek,CA.

Want back to using the ftp setup for forecast instead.

there is an example already entered by default
that is the format to follow
only 2 decmal places needed (will still work up to 4)

its likely the old method will be stopped updating by NOAA
