The National Hurricane Center in Miami named Irma a category 3 hurricane with maximum sustained winds of 185 kilometers per hour and higher gusts.
At 11 a.m. on Sunday, the system was located at 17.7 N – 48.4 W.
St. Maarten coordinates are 18.0425 N – 63.0548 W.
Based on these coordinates, the system was 38 kilometers south of St. Maarten and 1,622 kilometers to the east.
Moving at a speed of 22 kilometers per hour, it would take the storm around 74 hours to reach St. Maarten’s longitude. That puts the arrival of the storm at around noon on Wednesday.
Hurricane force winds extend up to 35 kilometers outward from the center of the system, narrowly missing St. Maarten at the current latitude.
Tropical storm force winds extend up to 130 kilometers outward from the storm’s center.
St. Maarten is therefore, based on the information available on Sunday morning at 11 a.m., in for some really bad weather.
