According to NOAA’s Storm Prediction Center, Tornadoes and waterspouts are possible across the entire Florida peninsula on Sunday and Monday due to severe weather conditions produced by Subtropical Storm Alberto.
The National Weather Service forecasts that squalls containing heavy rain will move northward up the Florida peninsula as Alberto tracks northward over the Gulf of Mexico.
These showers and squalls will contain heavy rain and occasional lightning with gusty, possibly damaging winds.
Directional shear will be capable of supporting rotation and possible severe weather, including tornadoes and waterspouts.
Know the signs of a tornado:
NOAA cautions that weather forecasting science is not perfect and some tornadoes do occur without a tornado warning.
There is no substitute for staying alert to the sky. Besides an obviously visible tornado, here are some things to look and listen for that may indicate tornadic activity:
Strong, persistent rotation in the cloud base.
Whirling dust or debris on the ground under a cloud base – tornadoes sometimes have no funnel.
Hail or heavy rain followed by either dead calm or a fast, intense wind shift. Many tornadoes are wrapped in heavy precipitation and can’t be seen.
Day or night – Loud, continuous roar or rumble, which doesn’t fade in a few seconds like thunder.
Night – Small, bright, blue-green to white flashes at ground level near a thunderstorm (as opposed to silvery lightning up in the clouds). Those flashes indicate that power lines are being snapped by very strong wind, maybe a tornado.
Night – Persistent lowering from the cloud base, illuminated or silhouetted by lightning – especially if it is on the ground or there is a blue-green-white power flash underneath.
