No. However, a calm period during a thunderstorm with dark clouds still overhead is a possible warning sign. A green or yellow sky under these conditions is often informally associated with tornadoes, though in and of itself it merely indicates that a storm is very strong. Also be on the lookout for any sign of rotation in the clouds.
A blue cyclone flag indicates a cyclone has formed and may affect the area within 48 hours. Yellow alert flags indicate that the cyclone is 24 hours out. Red alert indicates that the destructive winds are forecast in the next 6 hours and immediately take shelter.
Strong rotations at the base of a cloud means a tornado is trying to form, and of course a funnel means take cover. There is of course the sign everyone knows, if there is a sudden calm after a dramatic storm, though this does not always occur. When a tornado strike is imminent you may notice a drop in air pressure and you will hear a loud rumbling that many relate to the sound of an oncoming train. Also in some areas you will hear tornado sirens going off.Most importantly, you should pay attention to weather alerts broadcast on TV, the radio, online, and through some smart phone apps. If you are under a tornado warning it means a tornado is either in your area or is likely to develop soon.
yellow to yellow brown yellow to yellow brown
A wide variety of cloud colors have been reported during tornadoes depending on how the parent storm is arranged and on the position of the sun. Tornadoes need thunderstorms to form so there will always be clouds overhead if there is a tornado. Sometimes the clouds have the typical gray color of a thunderstorm, sometimes becoming dark gray and even black. If the sun is relatively low the clouds may appear green, yellow, or even a greenish-blue.
because it is yellow in colour
No. Strange lighting is not uncommon if a thunderstorm occurs around sunset.
No it is not. A yellow sky and calm conditions would only be associated with a tornado if you are on the tail end of a thunderstorm, and even then it would merely indicate that the storm was leaving more often than it would indicate a tornado. The yellow sky is simply a product of the light from the low sun passing through dense storm clouds. The only true sign that storm might produce a tornado is rotation in the clouds.If you are concerned about the potential for a tornado check the website of the National Weather Service or a battery-powered weather radio.
No sky color necessarily means that a tornado will form. A yellow sky during or before a tornado is due to the fact that most tornadoes form in the late afternoon or early evening and often take place around sunset.
the atmosphere makes it look yellow
A blue cyclone flag indicates a cyclone has formed and may affect the area within 48 hours. Yellow alert flags indicate that the cyclone is 24 hours out. Red alert indicates that the destructive winds are forecast in the next 6 hours and immediately take shelter.
