Where Nolo sits on the scale

Reading this forecast honestly

These are the centre positions the NHC expects. The average track error at 48 hours is on the order of 60-70 nautical miles, and intensity is forecast less well than track - rapid intensification in particular remains hard to call. A storm arriving 100 miles from the projected point is an ordinary outcome, not a failure.

The centre line also is not the hazard. Damaging wind, rain and surge extend well away from it, frequently on one side more than the other. Never plan around the line.

We archive every advisory as it is issued, which means the earlier ones can already be checked against where Nolo actually went. See how accurate the forecasts have been.
