Hurricanes. Extreme weather events that can strike anywhere in the world’s vulnerable zones. But where are these to be found? And in those zones, is there any historical evidence demonstrating that particular areas of the world are more vulnerable than others? A recent post on the very informative ABACO SCIENTIST website includes a comprehensive map of all hurricanes recorded since 1851. This map gives a clear picture of the hot-spots and danger areas.

The source is NASA and the article may be found HERE. I reproduce the map and explanation, with acknowledgement to John Nelson and IDV Solutions. Each blue link in the explanation below will take you to a new source of hurricane information, so the article is a valuable resource as a gateway to further hurricane knowledge.


“Should you be worried about hurricanes? To find out, it is useful to know where hurricanes have gone in the past. The Earth map shows the path of every hurricane reported since 1851, Although striking, a growing incompleteness exists in the data the further one looks back in time. The Earth map graphically indicates that hurricanes — sometimes called cyclones or typhoons depending on where they form — usually occur over water, which makes sense since evaporating warm water gives them energy. The map also shows that hurricanes never cross — or even occur very near — the Earth’s equator, since the Coriolis effect goes to zero there, and hurricanes need the Coriolis force to circulate. The Coriolis force also causes hurricane paths to arc away from the equator. Although incompleteness fogs long term trends and the prevalence of hurricanes remains a topic of research, evidence is accumulating that hurricanes are, on the average, more common and more powerful in the North Atlantic Ocean over the past 20 years.”

The image below was shared on Facebook, but I don’t have the inventor’s name. I’m sorry not to be able to identify the originator of this ingenious hurricane warning. Every home should have one…
