An alternative to costly radar-based weather services could soon be operational in developing nations, to help them detect severe storms more cheaply and quickly.

The technology, which uses lightning detection to forecast when and where storms will strike, has already proven successful in demonstration projects in Brazil, Guinea and India. Next year, Earth Networks — one of the companies at the forefront of the technology — will conduct further trials in Haiti.

As more developing nations increase their numbers of mobile phone masts, which are ideal locations for mounting the lightning sensors on, the proportion of countries using the technology looks set to increase, according to the US company.
