Storm Size and Speed

Storm size and speed are critical factors that influence the impact of a storm, particularly in terms of wind damage, rainfall, and storm surge.

Storm Size

• Large Storms: Bigger storms can affect a wider area, causing prolonged winds and rainfall. The wind field of larger storms can lead to extensive damage over a broader region.
• Small Storms: While they may have high wind speeds, smaller storms can have a more localized impact. However, they can still produce intense effects within their limited area.

Storm Speed

• Forward Speed: The speed at which a storm moves can affect how long it impacts a specific area. A slower-moving storm can lead to extended periods of heavy rainfall and wind, increasing the risk of flooding and damage.
• Rapidly Moving Storms: These can bring quick bursts of strong winds and rain, but the impacts may be more concentrated and short-lived.

Combined Effects

• Prolonged Effects: Slow-moving, large storms can lead to catastrophic flooding, especially if they bring heavy rainfall over several days.
• Storm Surge: The size and speed of a storm also influence storm surge. A slow-moving storm can push water toward the coast for a longer time, potentially leading to higher surges, while a fast-moving storm may create a less intense but still dangerous surge.
