Signals or Warning Signs Of A Hurricane
There are a few signs, such as an increase in ocean swell, wave frequency and driving rain, can be seen 36 to 72 hours before a hurricane strikes. Most warning signs are not apparent until it’s closer to making landfall.
Around 72 hours before a hurricane makes landfall, ocean swell increases to about 6 feet in height. Waves hit the shore about every nine seconds. This is one of the earliest signs of an approaching hurricane. As the hurricane gets closer to land, waves will hit the shore with greater rapidity and increase to as much as 16 feet in height.
The barometer begins to drop roughly 36 hours before a hurricane makes landfall, slightly when the hurricane is still 30 hours away and steadily plunging as the storm nears.
