Maximum sustained wind speeds were near 70 mph, and the storm was still predicted to strengthen into a category one hurricane - the lowest on the five-point hurricane scale, with winds of up to 95 mph.
Later that day, the JMA estimated that Betty attained its peak maximum sustained wind of and a minimum barometric pressure of 890 mbar.
Super Typhoon Vanessa was the strongest typhoon of the season, reaching maximum sustained wind speeds of 190 mph over the open waters of the West Pacific.
The maximum sustained wind occurred at landfall around Atlantic City of about 80mph.
Second, what the storm's maximum sustained wind speed was at that time.
The maximum sustained wind speed increased by 80 mph over that time, resulting in a storm with gusts exceeding 200 mph.
And now there is Patricia, forecast to soon hit Mexico, with currently estimated maximum sustained wind speeds of 175 knots or, that's right, over 200 miles per hour.
The National Hurricane Center said in a bulletin that Florence has been downgraded to a tropical storm, with maximum sustained wind speeds having decreased to near 70 mph.
Less than an hour after Patricia made landfall as a Category 5 storm — the fiercest — the National Hurricane Center said it was barreling inland over southwestern Mexico with maximum sustained wind speeds of 160 m.p.h.
These include the maximum sustained wind, radius of maximum winds, the Holland-B parameter, the peripheral or far-field pressure, the surface roughness and coefficient of drag, and the central pressure for historical hurricanes in the Gulf.
The intensity of a typhoon is measured by the maximum sustained wind speed, but the damage caused by its high winds, storm surges, intense rains and floods increases disproportionately, meaning a 15% rise in intensity leads to a 50% rise in destructive power.
