In heat lightning you see the flash of light from the lightning, but you don’t hear the thunder the lightning produces.
All lightning produces thunder when the bolt heats the air around it. This rapid heating causes the air to quickly expand and generate a sound wave known as thunder, which travels through the atmosphere.
As sound waves travel through the open air, they can change the direction in which they are traveling. In the lower atmosphere, the temperature of the air generally is cooler with increasing height above the ground. Cooler air over warmer air causes the sound wave to bend upward away from the ground. In this condition, you may see the lightning but not hear the thunder.
In warmer climes, palm trees are well-adapted to high-wind conditions, so there's no need to prune them, but remove coconuts and store them safely indoors. Check that all vining plants are secured to their supports, and that the supports are firmly staked into the ground. If they don't feel secure, remove the supports and lay them – and the plants – on the ground until the threat passes.After the storm Once the storm has passed, clear away fallen fruit and vegetables, which could attract rodents if left to rot on the ground, and remove protection from around plants.
