| SHIPS had 55 knots as the initial intensity. SHIPS version that takes land into account up to 93 knots (107mph) in 36 hours. 109 knots (125mph) for LGEM at that time. 69% chance of 45 knot increase in 36 hours. That would be 100 knots. (115mph) And then I suppose these would be if it wasn't onshore yet, but I don't know, so be cautious with these: 45% chance of 55 knot increase in 48 hours. That would be 110 knots. (127mph) 59% chance of 65 knot increase in 72 hours. That would be 120 knots.
