NYC Monthly Summary: November 2016

November felt like a weather roller coaster in New York City this year. We had highs that ranged from a relatively balmy 72°F to a chilly 41°F. However, with 19 out of 30 days posting above average readings, the warmth won out in the end. The city’s mean temperature for the month was 49.8°F, which is 2.1°F above our long-term norm. This was the Big Apple’s 17th consecutive month with an above average temperature – its longest streak on record.

In terms of precipitation, November was unusually wet and marked the first month since July that NYC received above average rainfall.  In all, we received 5.41 inches of rain which is 1.39 inches above normal. The majority of this plentiful total fell during two separate heavy rain events. In fact, November 29th was the city’s wettest day of the year and set a new daily rainfall record with 2.20 inches measured in Central Park. Nonetheless, despite these soakers, NYC remains in a moderate to severe drought according the latest report (12/1) from the US Drought Monitor.

Rainstorm Brings NYC its Wettest Day of the Year

A rainy day in New York City is typically nothing to write home about, but Tuesday’s precipitation was extreme. Heavy downpours brought the city more than half a month’s worth of rain in a single day.

According to the NWS, 2.2 inches of rain was measured in Central Park. Not only is that a new daily record for the date, it was the wettest day the city has seen so far this year. On average, we normally get 4.02 inches of rain for the entire month of November.

Suffering through moderate to severe drought conditions for several months, this rainstorm was largely beneficial for the area even if did put a damper on the Rockefeller Center Christmas Tree Lighting Ceremony. That said, even more rain is needed to bust this drought completely. Year to date, the city’s rainfall deficit is 7.24”.

This type of heavy rain event, according to NOAA, is expected to become more common in the northeast as global temperatures rise and precipitation patterns change.

NYC Monthly Summary: October 2016

October felt like a weather roller coaster in New York City this year. We had highs that ranged from a balmy 85°F to a chilly 51°F.   But, in the end, the warmth won out. The city’s mean temperature for the month was 58.8°F, which is 1.9°F above our long-term norm.

On the precipitation side of things, the city received near average rainfall for the first time in months.

Of this total, 1.41 inches fell during a single heavy rain event on October 27th – the city’s wettest day since last May.

Hurricane Matthew Slams the Southeastern US

Hurricane Matthew, the 13th named storm of the Atlantic Hurricane Season, hammered the southeastern United States this weekend from Florida to Virginia.

Tearing up the coast as it trekked northward, Matthew made landfall near McClellanville, SC on Saturday as a category-1 hurricane with 75mph winds. It had reached category-5 status in the Caribbean – the first storm to do so since Hurricane Felix in 2007- but weakened as it moved toward the US.

Despite this downgrade, Matthew still packed a powerful punch. Its strong winds, flooding rains, and storm surge caused significant property damage and widespread power outages throughout the region. The death toll from this storm currently stands at 26 people from across five states and is expected to increase in the coming days.

With successive bands of heavy rain, Matthew also caused catastrophic inland flooding. In Fayetteville, NC – 100 miles from the coast – 14.82 inches of rain was reported. As a result, several rivers in the region rose to record or near-record levels and overflowed their banks, inundating communities.

All told, Matthew dumped 13.6 trillion gallons of water on Florida, Georgia, South Carolina, North Carolina, and Virginia before heading out to sea as a post-tropical storm. That is enough water to fill over 20 million Olympic-size swimming pools. The highest rainfall total, 17.49 inches, was reported near Savannah, GA.

The damage caused by Matthew is currently estimated at $6 billion.

Hurricane Hermine Batters Florida’s Gulf Coast

Hurricane Hermine, the eighth named storm and fourth hurricane of the 2016 Atlantic Hurricane Season, made landfall in the Big Bend region of Florida early Friday morning. It slammed the Sunshine state’s west coast from Tampa to Tallahassee with heavy rain and winds measured up to 80 mph.

The category-1 hurricane generated a 9-foot storm surge in Cedar Key and dumped more than 22 inches of rain in parts of Pinellas County, flooding many communities. The storm also downed trees and knocked out power to over 250,000 people. Only one storm related death was reported.

Traveling across Florida, Hermine was downgraded to a tropical storm. It is now in the Atlantic moving north along the eastern seaboard. Impacts such as powerful winds, heavy rain, coastal flooding, and dangerous rip currents are expected to be felt from Georgia to Connecticut this holiday weekend.

Hermine was the first hurricane to make landfall in Florida in eleven years.

Tropical Storm Colin Barrels into Florida

Tropical Storm Colin, the third named storm of the 2016 Atlantic Hurricane Season, made landfall in the Big Bend region of Florida on Monday. It slammed the northern part of the Sunshine state with heavy rain and sustained winds measured up to 50 mph.

According to the NWS, more than 10 inches of rain fell in the Tallahassee area and Gainesville posted its second wettest June day on record with 5.65 inches of rain reported. All this precipitation in such a short period of time caused widespread flash flooding. Storm surge flooding was also an issue for communities along the state’s Gulf Coast.

The storm, according to FEMA officials, downed trees and knocked out power to more than 45,000 people between Tampa Bay and Jacksonville.

Traveling across Florida, the storm transitioned to a “post-tropical” cyclone on Tuesday as it moved up the east coast and out to sea.

Colin was the first named storm to hit the Sunshine state since Andrea in 2013. It was also the earliest “C” storm on record to form in the Atlantic Basin.

NYC Monthly Summary: May 2016

May 2016 was an unusual weather month in New York City with some days feeling more like March and others like August.

Bonnie Makes Landfall as a Tropical Depression in South Carolina

Bonnie, the second named pre-season storm of 2016, made landfall on Sunday just east of Charleston, South Carolina on the Isle of Palms.

According to the NWS, Bonnie was categorized as a tropical storm on Saturday with winds as high as 45mph. But by the time it came ashore, its winds had fallen below 39mph – the threshold for a tropical storm – and was downgraded to a tropical depression. Despite this reduced status, the storm still brought heavy rain, flash flooding, and dangerous rip currents to the area.

Rainfall totals, according to the Charleston NWS office, reached as high as ten inches in some spots. Flash flooding in Jasper County even caused sections of Interstate 95 – one of America’s busiest highways – to close.

Remnants of Bonnie are expected to linger over the southeastern US for the next several days, bringing even more rain to the region.

The Atlantic Hurricane Season official begins on June 1st.
