So has it been an active or inactive year for hurricanes? It depends upon which ocean you are referring to. The Atlantic Ocean has been relatively quiet with only 5 named storms, 4 becoming hurricanes, and only one making landfall for about 12 hours. The other side of the continent, the Eastern Pacific, has been a much different story with 17 names named storms, 12 becoming hurricanes and several bringing very heavy rainfall to parts of the Desert Southwest. During this time, California remains drought stricken!
So how does this compare to normal? So far only 5 names storms: Hurricane Arthur, Hurricane Bertha, Hurricane Cristobal, Tropical Storm Dolly, and Hurricane Edouard have develop with only Arthur making landfall for about 6 hours.
The charts below indicate less half the normal number of storms have developed so far in the Atlantic. Although the season is far from over, the typical number is 11 with 6 becoming hurricanes and 2-3 becoming Cat 3 or greater.
The peak activity is usually early September so it appears this will be a below average season.
The month of October can still see hurricanes develop but they usually remain across the far southern Gulf of Mexico.
The Eastern Pacific has seen 17 named storms and it appears a few more might be developing this week. This has been an above normal season since typically only 8-9 hurricanes develop. So far we are up to 12 and counting!
Another update on the tropical storm/hurricane season will be posted in two weeks. Stay tuned!
