Moving too fast to intensify. Needs to slow below 10-12MPH to strengthen.

Read Issac's Storm-the very best real life re-telling of the 1900 Storm that hit Galveston.

Moving too fast to intensify. Needs to slow below 10-12MPH to strengthen.

Completely, 100% wrong. For whatever reason that myth has developed the last few years.

12 mph is 10 kts. Literally hundreds of storms have strengthened to hurricanes moving 10-20 kts.

Allen in 1980 went to Cat 5 three different times moving 20 kts or even higher at times.
