Read from the hurricane center's advisories against the coast the chart draws. A landfall is where the line between two places the advisories gave crosses the coast, its time and winds read between theirs. Tropical storm force winds are 39 mph or more, hurricane force 74 mph or more, as far as each advisory gave them reaching.

Intensity error: how far each forecast's strongest winds were from the storm's, in mph, the mean over every forecast scored; the number of forecasts beneath each. Lower is closer.

How each is scored, as the hurricane center scores its own: against where its advisories put the storm at each six hours, and only while the storm was a tropical or subtropical cyclone. Each model is taken from its run six hours before, carried to the hour and set on the storm's centre and winds then, as the hurricane center does with its own early models, so every forecast here was there when the official one was issued. Storm Station's is made from those models, never from the official forecast.
