![]() In all velocity images, red colors indicate wind moving away from the radar with green colors representing wind moving toward the radar. This is called radial velocity as it is the component of the target's motion that is along the direction of the radar beam. ![]() However, the only motion it can "see" is either directly toward or away from the radar. One of the best features on the 88d Doppler radar is its ability to detect motion. View a sample composite reflectivity image (scroll down). It is used to reveal the highest reflectivity in all echoes. It is composed of the greatest echo intensity (reflectivity) from any elevation angle seen from the radar. View a sample base reflectivity image.Ĭomposite Reflectivity images utilize all elevation scans during each volume scan to create the image. This image is available upon completion of the ½° elevation scan during each volume scan. There are two versions of Base Reflectivity image the short range version which extends out to 124 nm (about 143 miles) and the long range version which extends out to 248 nm (about 286 miles). Taken from the lowest (½° elevation) slice, it is the primary image used to "see what's out there". There are two types available on the web Base (or ½° elevation) reflectivity and Composite reflectivity.īase Reflectivity is the default image. Lifeguards can give you advice on waves if you’re planning to go into the water.These images are just as they sound as they paint a picture of the weather from the energy reflected back to the radar. If the arrow is parallel to or pointing away from land, the wave height is likely to be lower If the arrow points towards land, most of the waves’ power will reach It indicates how sheltered theīeach will be from these waves. The arrow shows the average direction of the waves 1-2 miles out to sea. Lifeguards can give youĪdvice on waves if you’re planning to go into the water. Period (more than 10 seconds) means the waves at the beach may be more powerful. This is the average number of seconds between one wave and the next, 1-2 miles out to sea. Read more about calculating the expected height of the waves at the beach. Water, keep an eye on the waves to stop you or your belongings being swept away. Individual waves out to sea or at the beach can be higher than this number. This is the average height of the waves, 1-2 miles out to sea. 11 Extreme - Avoid being outside during midday hours. 8-10 Very high - Spend time in the shade between 11am and 3pm. 6-7 High - Seek shade during midday hours, cover up and wear sunscreen. 3-5 Moderate - Take care during midday hours and do not spend too much time in the sun unprotected. No risk of UV - It’s safe to stay outside. UV exposure index and the protection required to help keep you safe: The higher the percentage of humidity, the wetter it will feel outside. If there is a lot of water vapour, the humidity will be Humidity is the amount of water vapor in the air. Visibility measures the distance at which an object can be clearly seen. Read more about how wind will affect you at the beach. The number is the average wind speed.īeware of offshore winds if you are using inflatables, paddle boards or kayaks. ![]() If the arrow points from land to sea, the wind The arrow shows the direction of the wind (up is north). The number represents the average wind speed expected at that time. The letters show the direction the wind is blowing The arrow shows the direction the wind is blowing. Strong winds are shown in bold for speeds of 29 mph or more. Wind gust shows the highest wind speed that you should encounter at that time, as winds peak and Idea of how the temperature will actually feel at the time. ![]() You can see the temperature in Celsius orįeels like temperature considers other factors, such as wind speed and humidity. This number shows the air temperature for the time period. Sleet, snow, hail and drizzle) will fall from the sky at a certain time. Chance of precipitation represents how likely it is that rain (or other types of precipitation, such as ![]()
