(a) Use the Saffir-Simpson Hurricane Wind Scale (see Table, p. 453) to determine the category of Hurricane Elena (Fig., p. 441).

▼Table Saffir-Simpson Hurricane Wind Scale

SCALE CATEGORY	WINDS (ONE MINUTE SUSTAINED)		SUMMARY*
SCALE CATEGORY	mi/hr	knots	SUMMARY*
1	74-95	64-82	Very dangerous wands will produce some damage
2	96-110	83-95	Extremely dangerous winds will cause extensive damage
3	111-130	96-113	Devastating damage wall occur
4	131-155	114-135	Catastrophic damage will occur
5	>155	>135	Catastrophic damage will occur

FIGURE Hurricane Elena over the Gulf of Mexico about 130 km (80 mi) southwest of Apalachicola, Florida, as photographed from the space shuttle Discovery during September 1985. Because this storm is situated north of the equator, surface winds are blowing counterclockwise about its center (eye). The central pressure of the storm is 955 mb, with sustained winds of 105 knots (121 mi/hr) near its eye.
