![]() Obviously, an 18-foot storm surge at high tide is that much worse than an 18-foot surge at low tide. ![]() Another factor in the severity of the storm surge is tide. Contrary to a popular myth, the storm surge is entirely wind-driven water-it is not caused by the low pressure of the eye. The peak storm surge is on the right-front quadrant (left-front in the Southern Hemisphere) of the eyewall at landfall, where on-shore winds are the strongest, and at the leading edge of the eyewall. In deep-water enviroments, such as the Hawaiian islands, storm surge will be enhanced by the rapidly decreasing ocean depth as the wind-driven surge approaches the coast. The exact storm surge in any given area will be determined by how quickly the water depth increases offshore. Historically, storm surge is the primary killer in hurricanes. In the Northwest Pacific, a typhoon that reaches 150 mph (241 km/hr) is called a Super Typhoon. Many buildings destroyed, or structurally damaged beyond repair. Hurricane force winds extend well inland.Ĭategory 5 – 137+ knots (157+ mph 252+ km/h). Severe coastal erosion, with permanent changes to the coastal landscape not unheard of.

In the Atlantic Ocean, East Pacific, Central Pacific (east of the International Dateline) and Southeast Pacific (east of 160☎) a Hurricane in the Northwest Pacific (west of the International Dateline) a Typhoon in the Southwest Pacific (west of 160☎) and Southeast Indian Ocean (east of 90☎) a Severe Tropical Cyclone in the North Indian Ocean a Severe Cyclonic Storm and in the Southwest Indian Ocean (west of 90☎) a Tropical Cyclone. When the winds are sustained (based on a one-minute average) at 74 mph (64 knots 119 km/hr), the storm becomes: Tropical storms are named in the Atlantic, East, Central and Northwest Pacific, in the South Indian Ocean, and in the Arabian Sea. As the system strengthens, it becomes a tropical storm with winds from 39 to 73 mph (35-63 knots 63-118 km/hr). MINIMUM CENTRAL PRESSURE.993 MB.29.33 INCHESĪ hurricane (or typhoon, or severe tropical cyclone), the strongest storm on Earth, is a cyclonic (rotary) storm that derives its energy from cloud formation and rainfall, unlike frontal cyclones that derive their power from a temperature gradient.Ī hurricane begins as a tropical depression with a sustained wind speed of less than 39 mph (35 knots 63 km/hr).
