or less.
c. Tropical storm: Wind speed range of 63 to 117 km/hr 39 to 73 miles per
hour (34 to 63 knots).
d. Hurricane: Wind speed 119 km/hr 74 miles per hour or more (64 knots).

1.2.2 Weather Warnings
Weather warnings are issued for expected wind velocities. The following
are international terminologies issued for weather warnings:

a. Gale warnings: Issued for expected wind velocity of 63-87 km/hr 39-54
miles per hour (34-47 knots).
b. Storm warnings: Issued for expected wind velocity of 89-117 km/hr
55-73 miles per hour (48-63 knots).
c. Hurricane watch: Issued for hurricane conditions within 36 hours.
d. Hurricane warning: Issued for sustained winds of 119 km/hr 74 miles
per hour (64 knots) expected in 24 hours or less.

1.2.3 Wind Velocities
Wind velocities for tropical cyclones and weather warnings are
