Flood watch issued for metro and eastern counties as rain risk rises
What caused the issuance of the flood watch?
A flood watch means conditions are favourable for flooding, but flooding is not occurring at this time. The watch is for the potential of heavy rain developing over the metro area and eastern counties. Storms passing over and over again can quickly drop water on roads, fields and around small streams.
It can rain very hard in a short period of time.
Lower-than-road-level roads could be dangerous.
Small creeks and streams can get high fast.
Urban drainage systems get overloaded.
Where is it most likely to rain?
The main concern for metro communities and counties farther east will be repeated showers and thunderstorms that could bring the heaviest rainfall totals. While not all neighbourhoods will be flooded, areas near rivers, underpasses, construction sites and streets with poor drainage should be monitored closely during the event.
When could flooding be a problem?
Steady rain or stronger thunderstorms could cause flooding. The risk may be higher in the evening and at night because of slower drainage and less visibility. Drivers are being urged to take extra care with flooding able to develop quickly on roads, particularly after a number of rounds of rain.
Watch the conditions, especially if it’s pouring.
If you can avoid travelling in heavy storms, then do so.
Turn away from standing water.
Check local alerts before you leave
Clear vehicles from flood-prone streets.
What is the rainfall forecast?
Rainfall can vary greatly from place to place. Some locations may only see moderate rain but other locations could see heavier totals if thunderstorms train over the same location. “A few inches of rain in a short period of time can cause flash flooding in urban and low-lying areas.
What can residents do at this point?
People are being warned to expect the worst of the rain. Simple steps help you react quickly to warnings and lower the risk. Charge phones, turn on emergency alerts and secure outdoor items so they don’t clog drains or float away.
Clear leaves and debris from drains near your home.
Keep flashlights and batteries available.
Store an emergency kit with water and medicine.
Know a safe way off low-lying roads.
Why are cities more vulnerable?
Pavement, buildings and parking lots keep water from soaking into the ground, which is why metro areas flood so quickly. Storm drains can be overwhelmed by quick heavy rain. It can cause street flooding, vehicles stranded and conditions that are dangerous in underpasses and busy intersections.
How To Safely Drive In Heavy Rain
Heavy rain can be dangerous to drive in, as it is often hard to judge the depth of the water. What looks like an open road may hide fast-moving currents or broken pavement. Drivers should slow down, increase the following distance and turn around if they encounter flooded roadways.
Don’t go through flooded roads.
Slow down and avoid hydroplaning.
Turn on your headlights when visibility is reduced.
Avoid roads that have been closed.
Get there early.
What’s the difference between a watch and a warning?
A flood watch means flooding is possible. A flood warning means flooding is occurring or will occur soon. “Residents need to take a watch seriously because conditions can change quickly. A warning may be indicative of an impending threat to life and property.
When does the flood watch end?
A flood watch could be in effect until the threat of rain is over and the water level begins to go down. Runoff can cause problems even after the rain stops. But people still need to be cautious in swollen creeks, on wet roads and in areas where water tends to build up slowly.
