Point size reflects probe volume in the reference window. Worst hour needs four consecutive measured fifteen-minute bins. In Through time, playback interpolates between measured fifteen-minute bins and across gaps for display only. Gray points are outside measured coverage. Negative percentages mean fewer replies than the reference window.

The Southeast view includes candidate cities far from the storm, such as in Kentucky and West Virginia. Their changes are not attributable to Isaias.
