Flood Watch issued for NYC from Friday through Saturday

/by

The National Weather Service has issued a Flood Watch for the entire NYC Metro from Friday evening through Saturday. Locally heavy rain is expected to produce the potential for flooding in some areas. 1-2″ of rain is currently expected but locally higher amounts up to 4″ are possible. 

Right off the bat, it’s worth noting that this event is not similar to the one which brought significant flooding to NYC last Friday. However, it is still expected to be impactful with periods of steady or heavy rain and flooding – especially in poor drainage or low lying areas. The heaviest rain currently looks likely to fall from the late morning into early afternoon hours on Saturday.

What to Expect From Hurricane Lee in NYC

/1 Comment/by

It has been almost a week since Hurricane Lee formed, and five days since the headlines got out of control. “Hurricane Lee may be headed for New York”, we heard. “The storm may make landfall in New Jersey”, someone said on a TikTok. As we know, none of these things were true then and they still aren’t now. Hurricane Lee is not going to come close to making landfall in New Jersey or New York City.

Tropical Storm Lee formed this afternoon, designated by the National Hurricane Center just hours after the same system was declared Tropical Depression Thirteen. The storm is forecast to strengthen into a major hurricane as it moves towards the Lesser Antilles this weekend. The track thereafter remains uncertain, but east coast impacts cannot be ruled out.

The Dew Point Is the Best Way to Measure Your Misery 

/1 Comment/by

After walking outside and instantly sweating through my shirt a few days ago, I found myself in a very familiar position – hot, tired and uncomfortable. It was another summer day in New York City.

You know, the ones where the subway smells like a curious mixture of old Chinese food and body odor at 7:30 am. Where the ice in the $6.00 coffee you purchased from Starbucks 32 seconds ago already has already completely melted. One of those days.

The funny thing about that disgustingly humid morning is that when I went to check my phones weather app, it told me that the relative humidity was only 53%. That’s right, folks! Fifty-three percent. With a temperature of 88° F and a dew point of 69° F, miserable conditions under any circumstance, the relative humidity was only 53%. 

Which leads us to our most important point: The dew point is the best way to measure your misery. 

Dew point is an absolute measure of the amount of moisture in the atmosphere, while humidity is a relative measure of dew point as it relates to the temperature. 

In more technical terms, the dew point is “The temperature where any air mass when cooled to that temperature reaches 100% humidity. It is expressed as measure of degrees.” Humidity, on the other hand is defined as “The ratio of water vapor in the air to the maximum amount of water vapor in the air that could be present if the air were completely saturated at a given temperature.” 

By nature, the dew point is a better measure of how humid it feels outside because it is not relative to anything else. It is absolute, direct and stands alone as the single best measure for how miserable you’re going to feel upon walking outdoors.

That’s why we created our realistic dew point chart. It gives us a way to measure how miserable we are going to be on a given day. The prime time dew points generally range from the upper 40’s to the 50’s, leading to maximum comfortability. Below 40 is generally too dry/chapstick weather and above 65 is when the instant-sweat conditions return. 

Today, we’re expecting dew points to move solidly into the “instant sweat” level and perhaps even close to “hellscape” level – it’s disgusting out there. We should start to see some improvement by tonight and especially by early next week. September is notorious for bringing a handful of sunny, lower dew point days where New York City really shines.

With that in mind, forget about relative humidity and start checking the dew point before you head outside. You’ll be grateful that you did!
