Storm surge is generally made stronger by several factors:
- Stronger winds.
- Larger area covered by strong winds.
- Longer duration at a higher intensity.
- Lower barometric pressure, though this is a smaller contributor.
- High tide, though not a component of storm surge, can add to it in what is called a storm tide.
The opposites of these will lead to a small storm surge.
Originally storm surge was correlated with wind speed alone, but this was discarded.
Examples:
- In 2004 Hurricane Charley struck Florida as a strong category 4 hurricane. This would normally bring a very large storm surge, but the storm was small and had only recently intensified from a category 2.
- In 2005 Hurricane Katrina struck the Gulf Coast as a category 3, but due to the storm's enormous size and having recently weakened from a category 5, it had an enormous storm surge.

What factors make a storm surge weaker?
The main factors affecting storm surge strength are prevailing winds and the tide. Local geography also plays a significant role.
A local rise in sea level near the shore that caused by strong winds from storms such as those from a hurricane?
A storm surge.
What is used to measure storm surge?
Tidal gauges usually measure the storm surge.
Can a storm surge result in a hurricane?
No. It's the other way around: a hurricane causes a storm surge.
What contributes the storm surge?
"Storm surge" is the above-normal water level caused by tropical storms, especially by the high winds. The storm surge can be higher or lower than otherwise might be the case depending on the tides; a storm surge at high tides can be far more destructive than the storm at low tides.

What is a storm tide?
A storm tide is a storm surge caught in high tide, which causes stronger damage.
What part of speech is storm surge?
"Storm surge" is a noun.
A local rise in sea level near the shore that caused by strong winds from storms such as those from a hurricane?
A storm surge.
Does a storm surge bring cooler and drier air?
No. A storm surge is a bulge on the surface of a body of water created by a strong storm such as a hurricane. The storm surge can bring coastal flooding.
What is used to measure storm surge?
Tidal gauges usually measure the storm surge.
Can a storm surge result in a hurricane?
No. It's the other way around: a hurricane causes a storm surge.
What category hurricane has a stormm surge 9-12 feet?
Originally, a storm surge of 9-12 feet was listed for a category 3 hurricane. This association is no longer used as storm surge is influenced by more than just the sustained wind speed used to determine a hurricane's category.
What contributes the storm surge?
"Storm surge" is the above-normal water level caused by tropical storms, especially by the high winds. The storm surge can be higher or lower than otherwise might be the case depending on the tides; a storm surge at high tides can be far more destructive than the storm at low tides.
Where is a storm surge located in relation to a storm?
A storm surge occurs over water. It is a rising of the sea as a result of atmospheric pressure changes and wind associated with a storm.
Why was there a storm surge for hurricane sandy?
Hurricane Sandy produced a storm surge for the same reason that all other landfalling hurricanes do. The large area of strong winds from a hurricane essentially pushes the seawater onto land. Although other hurricanes have had far stronger winds than Sandy, that storm's extremely large wind field produced a high storm surge, which was made even worse as it was funnel up Long Island Sound.
Is the storm surge in the middle of the hurricane?
No. While the storm surge is worst at the center of a hurricane, it extends beyond that center.
