I agree that, barring a hoax, this conclusion is the likely explanation. They certainly are not mirage images and it's depressing that ITN (apparently) can be so silly. The talk of "heavy downpours" and "humidity" is relevant to the very obvious heavy cloud and local mist that we can see obscuring any possible optical raypath near the horizon and making any sort of mirage impossible, but is completely irrelevant to the mechanism of mirage. "It is believed that the sight may have been a mirage - a form of illusion that is common in in humid weather. The phenomenon is caused when moisture in the air becomes warmer than the temperature of water below." Nonsense. Mirage is not common in humid weather and has nothing to do with water temperature. At visible wavelengths the refractive index of air is controlled by the temperature alone and temperature gradients cause mirages. The moisture content has almost no detectable effect at all.
