Just today I saw a seven day prediction for the path of the cyclonic storm. As the commentator points out, 2 days back, the same cyclone was predicted to be heading for Kutch, now it is likely to make landfall near Mumbai tomorrow. He says, towards the end, that the path prediction will change again tomorrow, depending on which way, and at what speed, the cyclone keeps moving.
The point about an OSM mapping of locust swarms is to be able to assess similar forecasts over the next few days. For instance, the cyclone, had it gone on towards Kutch, would not have affected the locust swarms much. But, if it hits Mumbai tomorrow, and continues moving inland North and East, will sweep right across the generally expected (but not precisely plotted, yet) migration of the locusts, and certainly disrupt it to some extent.
