Hurricane Katrina became a Category 5 hurricane on at around 7 A.M. central daylight time on August 28, 2005. The storm reached peak intensity 6 hours later, with winds of 175 mph and a central pressure of 902 millibars.
No. The highest category of hurricane is a category 5, which is open ended. This means that once a hurricane's winds reach the required 156 mph or greater, it is still a category 5 no matter how much stronger it gets.
Hurricane Katrina formed over the Bahamas on August 23, 2005 and crossed southern Florida as a moderate Category 1 hurricane, causing some deaths and flooding there before strengthening rapidly in the Gulf of Mexico. The hurricane strengthened to a Category 5 hurricane over the warm Gulf water, but weakened before making its second landfall as a Category 3 hurricane on the morning of Monday, August 29 in southeast Louisiana
The highest winds recorded in a hurricane were 190 mph. More specifically, Typhoons Tip, Keith, Vera, Sarah, and Hurricanes Allen and Camille are the only tropical cyclones to record a 190 mph sustained wind. However, a recon estimate within Typhoon Nancy (1961) reported sustained winds of 215 mph. However, wind speed estimates at the time were deemed as overestimates, and thus 215 mph from Nancy is not verifiable record.
There are 5 different categories a hurricane can reach 1,2,3,4 and 5. as most would suspect 5 is the highest and extremely dangerous. These categories are determined by the highest winds a hurricane sustained over the course of 1 minute. Category 1: 74-95 mph Category 2: 96-110 mph Category 3: 111-129 mph Category 4: 130-156 mph Category 5: over 156 mph Category 5 winds have been measured as high as 190 mph.
When winds reach or exceed 156 mph a hurricane is considered a category 5.
Hurricane Rita reached category 5 strength over the eastern Gulf of Mexico.
Hurricanes are named alphabetically in the order that they reach tropical storm status. It restarts every year, Katrina was the name of the Hurricane that hit New Orleans in 2005, it was the 11th tropical storm of that year.
up to 155 or more but nobody knows exactly the miles per hour it can reach bit the highest record of an hurricane was hurricane Camille at 190 mph
Hurricane Rita was the next actual one that made landfall and was substantial.
the category of the hurricane was when the hurricane came toresed us we all whent under ground to be safe in sound
When the wind speeds reach 74 miles per hour they are then classified as a category 1 hurricane.
This is no given diameter. Hurricanes are rated based on wind speed, not size. A hurricane is classified as a category 5 if sustained wind reach or exceed 157 mph.
