Rare red sprites known as espectros rojos were captured over Cabo Rojo, Puerto Rico, during thunderstorms associated with the remnants of Tropical Storm Dolly.[^1]

The phenomenon occurred as electrical discharges lit up the sky above the western municipality while the storm system moved through the island.

The read here is that these high-altitude electrical discharges are a rare atmospheric event, yet they have been documented in Puerto Rico before this specific instance linked to Dolly's remnants.
