The wind is coming, the rain is coming and the sky is dark.

You’ve got to have a plan.

But what if you don’t?

The forecast for the weekend is for heavy rain and winds across the north-east, with the threat of heavy flooding expected.

Image caption The wind has moved across the northern hemisphere and the rain has now settled in on the eastern coast.

The latest rainfall warnings for the northern coastal areas have been issued.

But even with the rain, it is not expected to make for a particularly beautiful weekend.

So what happens when the wind blows and the weather turns stormwater into rain, in this case?

A stormwater catchment is a collection of stormwater that collects and holds stormwater in place during a storm.

The catchment can hold up to one metre of storm water, but as the wind moves, it can cause stormwater to collect on top of that.

The more rain you have in a day, the more stormwater you will have in the next day.

“The more that the wind is blowing, the deeper it is,” says Tom O’Hara from the Environment Agency (EA).

“The higher up in the sky, the denser the water will be.”

There’s a limit to how much rain you can get and how much stormwater there is to collect, and how many people can come through the water.

“And if there is enough water to collect at all, that means the wind has blown it deep enough to be a hazard to people.”

You can’t go swimming in it,” says Mr O’Hea.”

It is very, very difficult to get in.

“What you need to know about the Storm Surge Warning SystemThe Storm Surge Watch is an alert issued when a maximum of 12.5mm (0.6in) of rainfall falls across a 5km (3.6m) radius of a coastal area, meaning the water can reach up to 20 metres (65ft) in depth.

A collection of catchment water is stored in a reservoir, which can hold 1.5m (6ft) of water, depending on the depth.

In the worst-case scenario, where the wind speed is 200km/h (125mph), the amount stored in the catchment will be 25 times what it would be in a normal storm.

In an ideal situation, the water is pumped from the surface, and then carried to the surface by the storm.

It can be very slow, but it can be done and people are always able to get to them.

A major storm surge is an increase in water level that occurs as a result of a surge in the ground that occurs in a single day.

This could be when a large amount of rainfall is forecasted, or the wind speeds are too strong for a rain-snow pattern.”

In a normal flood, the ground has been breached by rain and then the floodwaters have flooded over, and they’ve created a large river in the river,” explains Dr Michael Brown from the University of Melbourne.”

So you’ve got that river going into the sea, and it’s now flooding the sea.

“What does that mean?

A massive amount of flooding can occur when a massive amount in a short period of time.”

We have seen a huge amount of rain over the last few days, but what happens if that rain falls on top, the stormwater will pool on top and it will flood the river?” asks Dr Brown.”

And then the water level will be too high to carry the water out into the ocean, and the storm will just flood again.

“What can you do to protect yourself?

The warning is triggered when the water depth rises above 6.5 metres (19ft).”

A big concern in the coastal flood area is when the storm surge gets to 6.6 metres (21ft), that means there’s a huge chance of water coming into the river and flooding,” says Dr Brown from Melbourne’s Monash University.”

That’s when the warning can come in.

“The biggest danger of the coastal flooding is when it occurs in large quantities, as it can lead to severe flooding in the low-lying areas.”

A storm that has the potential to
