Hurricane Harvey is showing strong lightning activity in at least two bands in its north-eastern quadrant. Thunderstorm activity is usually associated with a strengthening of the cyclone, so Harvey may even become a strength 3 hurricane.
Last year's hurricane Matthew produced a large number of sprites during such a phase, indicating very strong positive lightning.
