Hi!
Just add a second geom_contour()/geom_contour2() call with breaks = 1015 and increase its size.
from ggnewscale.

sorry eliocam opening this again.
I am still struggling with my attempt to add a thicker 1015 hPa contour line using below command. Could you help me adjust the code? something looks incorrect.
Thanks

Hi, your code is very complex and I cannot run it because I don't have the data. You can draw a single thick contour line at 1015 hPa with geom_contour(...., breaks = 1015, linewidth = 1), where ... represents any other arguments such as the data, aesthetics, etc.
from ggnewscale.

OK, I see no problem.
Thank you again
