As the event becomes imminent, a watch will normally be upgraded to either a warning or an advisory (which indicates an 80% or greater probability of occurence). A Warning indicates that conditions pose a threat to life or property, and that travel will become difficult to impossible.

Thunderstorms and tornadoes: watch means the there is a potential for severe weather to develop, the conditions are right. A warning means a severe storm or tornado has been spotted.

What causes Tornadoes? Thunderstorms act as Earth’s cooling agent by drawing hot moist air from the ground. When temperatures are different between the ground and atmosphere, the air rises quickly, condenses, and forms thunderheads. These winds are forced into an upward spin, starting the formation of a tornado.

sea levels rising due to high waves. coastal flooding due to storm surge. paths of damage up to 50 miles long.

Explanation: Tornado is the rapid and violent rotation of column of air which move from the thunderstorm to the ground. It is formed when there is collision between warm and cold air. The cold air which is more sense than the warm air is pushed over the warm air which result in thunderstorms.

Go to a basement. If you do not have a basement, go to an interior room without windows on the lowest floor such as a bathroom or closet. If you can, get under a sturdy piece of furniture, like a table. DON’T STAY OR GO TO THESE DURING A TORNADO!

Go to the basement or an inside room without windows on the lowest floor (bathroom, closet, center hallway). If possible, avoid sheltering in a room with windows. For added protection get under something sturdy (a heavy table or workbench). Cover your body with a blanket, sleeping bag or mattress.

Tornado safety precautions

• Go to the lowest and smallest room.
• Get under something sturdy or in a hallway.
• Get away from windows.
• Cover yourself from blankets, pillows and coats to protect you from debris.
• Crouch as low as possible to the floor.
• A bathtub may also offer a shell of partial protection.

The answer is when the waves meet the shore and cause the crest to spill over the trough. This activity creates a back and forth movement of the sand which causes them to settle at a certain area under below the water.

In fluid dynamics, a breaking wave or breaker is a wave whose amplitude reaches a critical level at which some process can suddenly start to occur that causes large amounts of wave energy to be transformed into turbulent kinetic energy.

Spilling breakers occur as waves travel across a gently sloping bottom (i.e., gently sloping sea floor near the beach). The wave breaks long and slow, losing its energy as white water spilling from the crest down the front of the wave.

When the Energy Meets the Ocean Floor As waves reach the shore, the energy in front of the wave slows down due to friction with the shallow bottom. The wave breaks, and it usually does so in water depth that is 1.3 times the wave height.

You can also call them- breaker, breakers, or surf. waves breaking on the shore. a heavy sea wave that breaks into white foam on the shore. (

So the first wave in a group is tiny, the next one is bigger and so on until you get the biggest one in the middle of the group. Then they get smaller again. The last one is tiny, so the biggest wave in the group is in the middle, and if there are 14 waves in a group, the seventh wave is the biggest.

Waves are dependent on three major factors – wind speed, wind time and wind distance.

When waves approach the shore they will “touch bottom” at a depth equal to half of their wavelength; in other words, when the water depth equals the depth of the wave base (Figure 10.3. 1).

A scientific term to describe waves that don’t have time to break because the transition from deep-water to shallow water is too fast so they end up just surging up onto the beach. Very little white water is evident before surging waves reach the shore.

There are four basic types of breaking waves: spilling, plunging, collapsing, and surging. Spilling waves are gentle waves with crests that break softly towards the shore. These waves break when the ocean floor has a gradual slope. Plunging waves break when the ocean floor is steep or has sudden depth changes.
