Hurricane Preparation

As we all know, the Hurricane Season will soon be upon us. The season runs from June 1 through November 30th. In preparation of what some predict to be an active season, your Office of Emergency Management is reviewing its policies and procedures to insure that proper decisions are made in the event we are threatened by these potentially catastrophic storms.

The most active months of hurricane season are August, September, and October. During summer and late fall, the air over the warm ocean gets hot, picks up moisture and starts swirling and a tropical depression is born. Once the winds exceed 39 miles per hour, it becomes a tropical storm. When the winds exceed 74 miles per hour, the storm is classified as a HURRICANE and given a name.

Hurricanes are classified through a scale called the SAFFIR/SIMPSON HURRICANE SCALE. This scale classifies each hurricane by its disaster potential with the category 1 being a minimal storm and category 5 being a catastrophic event. The complete scale is as follows:

Category

Catastrophic
It should be noted at this point, that the Bay Surge is always greater than the Coastal Surge due to the funnel effect created by a large body of water (The Gulf) dumping into a smaller body of water. (Galveston Bay).

As a part of this preparation process, the City of Seabrook, Office of Emergency Management will again participate in the annual State Hurricane Polly Exercise, which commences prior to the start of hurrincane season each year. Through this exercise, we will examine pre landfall activities, landfall activities, and recovery operations.

As your Emergency Management Coordinator, I urge you to plan for this upcoming hurricane season. Remember that Seabrook does NOT have PRE-LANDFALL SHELTERS.

Should you have any questions regarding hurricane preparation or any other topic dealing with emergencies and disasters, please feel free to contact me at (281) 291-5611 or e-mail me at nholomon@seabrook-tx.com
