John P. Cangialosi: Hurricane Irma Discussion Number 12. National Hurricane Center, 2. September 2017, abgerufen am 7. September 2017 (englisch): „It is interesting to note that a ship (BATFR17) passed within 50 n mi to the west of the center of Irma and has only reported winds of about 40 kt, indicating that the core of Irma is compact.“
Lixion A. Avila: Hurricane Irma Discussion Number 15. National Hurricane Center, 2. September 2017, abgerufen am 5. September 2017: „The subtropical ridge building to the north of Irma has been steering the hurricane toward the west or 260 degrees at 12 kt. The ridge is forecast to amplify even more, and this flow pattern will force the hurricane to dive west-southwestward for a couple of days. Irma should then begin to gain latitude once it reaches the southwestern edge of the ridge in about 3 days.“
Robbie J. Berg: Hurricane Irma Discussion Number 16. National Hurricane Center, 3. September 2017, abgerufen am 7. September 2017 (englisch): „Irma has been losing latitude since yesterday due to strong high pressure to its north, and the initial motion is now west- southwestward, or 255/13 kt. The hurricane is likely to continue moving on this trajectory for the next 36 hours, after which time it should gradually turn toward the west and then west-northwest on days 3-5 when it reaches the western extent of the ridge.“
Daniel P. Brown: Hurricane Irma Discussion Number 17. National Hurricane Center, 3. September 2017, abgerufen am 7. September 2017 (englisch): „The first reconnaissance mission, a NOAA P-3 Hurricane Hurricane aircraft, is scheduled to depart Barbados for tail Doppler radar mission into Irma late this afternoon… A strong high pressure ridge over the central Atlantic is steering Irma west-southwestward or 255/12 kt.“
Robbie J. Berg: Hurricane Irma Discussion Number 20. National Hurricane Center, 4. September 2017, abgerufen am 7. September 2017 (englisch): „A strong, stationary mid-tropospheric high centered over the central Atlantic is forcing Irma on a west-southwestward course, and the initial motion estimate remains 255/12 kt. Irma will begin rounding the southwestern edge of the high soon, which will allow the hurricane to turn westward later today and then west- northwestward in 36-48 hours.“
