Experimental forecast storm probabilistic maps.

GEFS Spaghetti Plots. Streamlines for 850 hPa Control member. Spaghetti-o's consist of 20 pertubration members and 1 control.

Vorticity: Smoothed over 250 km radius to produce circulation. Purple outlines weak circulation, light blue indicates likely area of interest or TD, darker blue suggests strong low-level circulation posiibly TS or greater. Streamlines for 850 hPa control member. Numbers indicate percentage of ens members per spaghetti bundle.

PMSL: Closed contours around lows of ≤1012 hPa, where contour is low + 2 hPa. Therefore each member will only have 1 contour around each low. Contours coloured by central pressure minimum.
