Unbelievable numbers are coming out of Long Island this morning.

First and foremost let's start with 13. Islip, New York has registered more than 13 inches of rainfall since midnight Wednesday. I'll have to wait for verification by the National Weather Service before making any claims, but this is likely the most amount of rainfall from any event on record for this particular site. I have been in and out of the chatroom for New York's National Weather Service, and folks have been tossing around the stat that this rainfall breaks even the all time monthly rainfall record. Again I'll have to wait to get that finalized and confirmed by the NWS.

So what happened? Well a very intense low pressure system moving northeast along the coast, coupled with strong low level winds ushering in moisture from the Atlantic just dumped a ton of rain on central Long Island. Training cells (which means thunderstorms or heavy rain that continues over a localized area for a long time) resulted in a band of extremely heavy rainfall.

Unfortunately many people had to abandon their vehicles during the morning commute and water evacuations were underway. I have not heard of any injuries or fatalities but check back in with us for more on that. An unusually strong low pressure system for mid-August will give the Northeast that threat of flash flooding and very cool air for this time of the year.
