The last few hot days and a look at the hurricane season so far

I have attempted to catch up with more shorebirds and herons/egrets the last few days this week but the conditions have not been great. We have not had enough rain in the immediate area to leave any big puddles and the ones that have formed have been quickly dried out by our temperatures in the 90's. In addition areas to our north and west have gotten much more rain which has swelled the Connecticut River enough to cover any mud flats.  Nonetheless there are still birds to be seen but nothing unusual.
As the month of July rolls on I thought it would be time to look at the tropical season so far and what the future might bring. The long range forecasts continue to show a below average hurricane season for a variety of reasons including a strengthening El Nino, dry air over the Atlantic and high wind shear (among a number of other reasons). So far this season the Atlantic has featured three named storms with no development expected in the near term. The highest likelihood of development is in closer to shore where the conditions are more conducive at this time for tropical development. As fronts pass off the coast of the U.S. the potential is there for a tropical system to develop either along the east coast or in the gulf as opposed to development from a tropical wave coming off of Africa and travelling across the Atlantic. It will be interesting to see how this plays out over the next few months but overall the season looks to be below average but that doesn't mean we will not see impact from a tropical system only takes one storm with the right conditions to have a impact here. How it will relate to birding is also a tough question to answer and involves lots of speculation. If a storm were to develop in close to shore there are a number of birds that could be displaced. Along the coast of Massachusetts there has been a large (and growing number) of pelagic birds including a number of rarities. Whale watching trips and dedicated pelagic trips off of Massachusetts have been seeing large numbers of Cory's Shearwaters as well as Great, Manx, Sooty and Audubon's Shearwaters and Leach's, Wilson's and Band rumped Storm Petrels. At times some of these species have been seen in very large numbers from shore too. A storm moving through this area could easily displace these birds inland if the right conditions occurred. The list of rarities seen off the coast lately have included Fea's Petrel, a probable Yellow nosed Albatross and a number of unusual terns (including Bridled Tern). The warm water (and the species associated with it) are we just need a tropical system to occur to move them around to unusual locations inland. Although the chances are low for a storm to have the right conditions to bring birds into western Massachusetts at this time, a more likely scenario would see the Maritimes of Canada (and possibly Maine) getting a bounty of pelagic birds from a tropical system moving through.
