Could we get another tropical cyclone forming in May? It now looks possible. The NHC has given this system a 40% chance of development over the next 5 days. If it does form it would be the 7th consecutive season a pre-season tropical cyclone forms. Fortunately, it shouldn’t be a threat to any landmass.

Here Comes the Heat!

High pressure will remain in control resulting in hot weather Wednesday. Expect highs in the mid to upper 80's, but possibly in the low 90's for Manhattan and further inland. Fortunately, it looks like it'll be the dry heat as relative humidity will be less than 50% and dew points below 60. It will cool a bit for Thursday and Friday, but still be unseasonably warm with highs in the low to mid 80's.

For those anxiously awaiting the warmer weather, it looks like that permanent spring-summer warm up will finally come next week. The CPC is predicting a 70% chance of above-average temperatures over the next 6-10 days. The GFS reinforces this and shows temperatures in the 80's Wednesday through Friday next week.

What Would Happen if a Major Hurricane Struck NYC and Long Island - Part 2

So in terms of weather-related disasters what's in store for the future of New York? It's inevitable that we will be impacted by a category 2, 3, or 4 hurricane sometime in the future. However, because it's such a rarity public complacency has become a major obstacle to overcome. Approximately 78.5% of current New York State coastal residents have never experienced a major hurricane (Sandy was a category 1 equivalent sub-tropical storm at landfall). One must also take into consideration population growth. The last major hurricane to directly impact our area was the Long Island Express back in 1938. However, at that time Long Island was mostly underdeveloped. The next time a major hurricane hits, it will be impacting a highly-urbanized region so more people will be affected. As the population increases and building accelerates near the coastline, the economic damage from storms will increase as well. Yes, we've had a few storms since then (Carol, Gloria, Bob, Sandy), but they were mild compared to the Great Hurricane of 1938. Additionally, with population growth comes evacuation problems. Over 7.5 million people live on Long Island. Since there are very few evacuation routes off the island more lead-time is needed for a proper evacuation than in other parts of the country. However, getting that lead-time would be very difficult since east coast hurricanes normally get caught up in very fast winds aloft causing them to move up the coast at great speeds (a reason why a bridge across the Long Island Sound may be an excellent idea). After Miami and New Orleans, NYC is considered the third most dangerous major city in the U.S. for a major hurricane to strike (for reasons explained in my post a few days ago, which you'll find by scrolling down).

Surface high pressure offshore will keep the weather mostly dry and seasonably warm through the weekend. A surface trough though may bring some isolated showers and thunderstorms Sunday afternoon and evening.

Saturday: partly sunny; low to mid 70's, but a bit cooler east and near coast

Saturday night: partly clear; some sprinkles and drizzle possible; mid 50's

Sunday: partly sunny; isolated showers and thunderstorms possible during the afternoon and evening
Temps: low to mid 70's, but a bit cooler east and near coast
Precip: 30% after 1 pm (

What if a Major Hurricane Hit NYC and Long Island?

It's hurricane preparedness week, so we'll be discussing tropical cyclones and hurricanes the next few days. So let's kick it off by discussing what would happen if a major hurricane struck NYC today. Fortunately, this is extremely rare, but what if it did happen? By a hurricane I don't mean another hurricane Sandy. I mean a direct or near direct hit from a category 3 or 4 hurricane. Believe it or not, NYC might be one of the worst places in the world for a hurricane it to strike. This is due to the fact that NYC is extremely vulnerable to storm surge. Let's say a category 4 hurricane were to approach from the south and make landfall on Long Island just a little east of the city. The ocean water would be pushed into the NY Bight. A bight is a curve in the shoreline of an open coast that funnels and increases the speed and intensity of storm surge. As the hurricane approaches the winds would push the water into the Raritan Bay. As long as the winds keep blowing from the east the ocean water can only enter, not exit the bay. This results in rising water in northeastern NJ and in the upper New York Bay flooding areas such as Battery Park. The same would occur in the western Long Island sound as the storm moves further north. Water from the sound would pile up into the Eastchester Bay and East River. Computer simulations have shown that the surge could be anywhere from 20-30 feet in areas such as Staten Island, Coney Island, and Lower Manhattan. It would likely end up being the costliest disaster in U.S. history. According to hurricane probability models, there is a 2.6% chance that a hurricane will strike the NYC area in any given hurricane season. Also, there is 13.6% chance that a hurricane will affect the city during a 50 year period and a 3.3% chance of a category 3 or greater. Below is a map of predicted storm surge for a category 4 hurricane.

So what about Long Island? Landfall would first occur on the southern shore. Whichever part of the island is to the east of the eye will be the most vulnerable due to the south to north winds pushing the ocean water northward towards land (the twin forks would most likely be in that region). Also the low elevation of the southern shore would allow the surge to move well inland. A category 1 hurricane would inundate just about the entire immediate southern shore, including the north side of Great South Bay locations and both sides of the north and south forks. Montauk Point would become completely cut off from the rest of south fork. During a category 3 hurricane Montauk Highway would be completely covered by flood waters and much of the north and south forks would be entirely under water. A category 4 would cause the water level to rise over 25 feet in many areas. The surge would inundate the entire towns of Bayshore, Islip, Westhampton Beach, Valley Stream, Lindenhurst, Freeport, Wantagh, Amityville, Long Beach, Atlantic Beach, and many others.
