Glider Reachability Map Forecast for 07 Sep 1155Z to 17 Sep 1155Z 2025, Issued 07 Sep 2025

The black contours shown are reachability front forecasts, at 24 hour intervals (0hr to 240hr forecasts, with increasing line thickness for later times). The reachability front is the boundary of the largest set (the reachable set) that the glider can reach within that duration. It is computed by numerically solving our exact governing PDE for this time-optimal reachability front.

In this forecast, we consider the actual starting locations of the gliders at their last reported positions.

Each row in the table corresponds to an MSEAS reachability forecast for different assumed glider speeds: 20, 30, and 40 cm/s.
