    Maria, now a tropical storm, was situated at 12.3°N, 52.6°W. According to historic climatology, just under 1-in-5 tropical cyclones that formed within 100 nautical miles of Maria's area of development made U.S. landfall. However, a large number of those systems tracked generally westward, many dissipating in the process.

    The synoptic pattern as currently modeled argues against such a scenario. Therefore, excluding the systems that tracked generally westward and failed to make a turn more to the north, the smaller sample yields a landfall probability closer to 2-in-5. That's quite high.

    Notable systems that made U.S. landfall included Hurricanes David (1979), Frederic (1979), and Ivan (2004).

    At least for now, Maria bears watching.
     

    These write ups are great. What would be awesome is if you could do the day 3 and/or day 5 NHC forecast positions as well. Maybe even create a weighted average (maybe like 40% current, 40% d3 and 20% d5). Obviously would be a lot of work, assuming you do it manually, but it would be a genuinely helpful metric for forecasting.
