Floridians, grab your umbrellas! A brewing storm system has meteorologists keeping a close watch on the Gulf Coast this week.
The National Hurricane Center announced Monday, July 14, that they are monitoring a developing low-pressure system off Florida’s northern Atlantic coast. Forecasters warn that heavy rainfall could lead to localized flash flooding across parts of Florida and the north-central Gulf Coast through the latter half of the week.
While we hope for the best, it’s always wise to prepare for the worst. Getting ready for a hurricane well in advance is crucial.
Stocking up on supplies, planning evacuation routes, and securing your home can make a significant difference. Understanding the early warning signs of an approaching hurricane allows you to take necessary precautions.
Here are some key indicators to watch for:
Heightened Ocean Swell: One of the earliest signs of an approaching hurricane is a change in ocean conditions. Roughly three days before landfall, swells can reach around 6 feet high, with waves crashing every nine seconds. As the hurricane nears, these waves grow larger, hitting with increasing force and frequency, potentially reaching heights close to 16 feet.
Barometric Pressure Drop: About 36 hours before a hurricane makes landfall, barometric pressure starts to fall. Initially subtle, the drop becomes more pronounced as the storm approaches.
While some individuals may experience headaches or increased joint pain with dropping pressure, the most accurate way to monitor it is with a barometer. Lower pressure can also contribute to lower blood pressure in some people.
Increasing Wind Speed: Winds intensify as a hurricane approaches the coast. Starting at around 11 miles per hour roughly 36 hours before landfall, wind speeds can escalate to a staggering 104 miles per hour as the storm nears. The wind also becomes increasingly gusty, capable of dislodging unsecured objects and breaking tree branches.
Heavier Rainfall: Rainfall typically begins about 18 hours before a hurricane’s arrival. While initially intermittent, the rain intensifies as the storm draws closer, eventually becoming a continuous downpour about six hours before landfall. This heavy rainfall can also lead to flooding.
