Record Flooding Stops Subways in New York City!

Written by Team Morecast

 

Nearly stationary storms dropped record rainfall in portions of New Jersey, New York, and Connecticut late Monday. The sudden deluge caused serious flash flooding in the NYC metro, halting traffic both above and below ground. At least two people lost their lives when their car was swept off the road in Plainfield, NJ.

 

 

 

Slow-moving storms erupted first in the NYC suburbs mid-afternoon Monday before converging on the city early in the evening. The storms produced torrential rainfall rates up to 2″/hr (50 mm/hr), overwhelming drainage systems across the region. Central Park in Manhattan shattered a daily record with 2.64″ (67 mm). Most of this fell between 7-8 pm, the second-wettest hour ever recorded at that station. Other nearby stations saw as much as 3-6 inches (150 mm).

 

 

Runoff quickly covered roads and highways with 1-2 feet of water, forcing numerous road and highway closures. Hundreds of emergency calls were placed for water rescues from stranded cars. Subway lines were shut down as the runoff inundated platforms and tracks (see video above). Residents of basement apartments in NYC had to deal with sudden waist-deep water. Protocol changes following the tragic basement drownings in September 2021 seem to have helped avoid similar injuries and deaths in this case, fortunately. Lead photo courtesy MTA’s Marc Hermann.

 

Torrential Rainfall Leads to Sudden Flash Flood, Killing Dozens in Texas

Written by Team Morecast

 

A stationary storm dropped up to a foot of rain in a matter of hours overnight Thursday in central Texas. Runoff from these rains forced the Guadalupe River to rise 26 feet (7 m) in approximately 45 minutes (see river gage data below). Communities and camps along the river were inundated too quickly for an evacuation to be organized. Hundreds of people were caught and swept away by the the floodwaters. Unfortunately two dozen fatalities have been reported with dozens more still missing.

 

 

 

Much of the worst flooding has occurred near Kerrville, Texas, where the Guadalupe River rose to its second-highest peak on record. Hundreds of first responders have been called to the scene from across the state, including at least 14 search-and-rescue helicopters. Many of those still missing were attending Camp Mystic, an all-girls summer camp. Some of the campers and staff have been pulled from cars, unmoored structures, even clinging to trees above the floodwaters, but 23 are still unaccounted for as of Friday night.

Midwest and Eastern U.S. Broiling in Record-Breaking Heatwave

Written by Team Morecast

 

A massive dome of extreme heat has enveloped central and eastern portions of the U.S. in the last few days. Numerous major cities have set daily and even monthly high temperature records, putting a significant strain on water and power resources across these regions.

 

 

The heat built first over the Upper Midwest and Great Lakes on Sunday. Minneapolis saw a high of 96 deg F (35.6 deg C) on Sunday, setting a new daily record, while Chicago set a new record for warm overnight low Sunday night. The heat dome spread east for Monday and Tuesday, encompassing all the major cities along the Urban Corridor. At one point over 150 million Americans were under heat advisories or Extreme Heat Warnings (see image above). New monthly high temperature records were set in Boston, Massachusetts (102 deg F / 38.9 deg C), Providence, Rhode Island (100 deg F / 37.8 deg C), New York, NY (102 deg F / 38.9 deg C), and Newark, New Jersey (103 deg F / 39.4 deg C). Heat index values soared well into the 110s, greatly escalating the risk of heat stroke for anyone spending time outdoors.

 

 

The overwhelming strain on power grids caused thousands to lose power in several states, a significant danger when air conditioning is so essential. Rail commuters faced major delays as extreme heat caused significant speed restrictions due to the danger of track warping. The heat even caused hazardous buckling in roadways (see video above).

Unprecedented Flooding Wreaks Havoc Along New South Wales Coast

A torrential rain band has persisted along the north-central NSW coast for the past several days as an upper low remains parked over the region. This rain band has dropped widespread 300-500 mm (12-20 in) amounts, leading to tremendous runoff and severe flooding. Some rivers are reaching levels never before recorded, inundating numerous homes and businesses and forcing thousands to evacuate.

 

 

The rain band developed early Monday and has been wobbling slowly up and down the coast between roughly Newcastle and Coff’s Harbour. Rainfall rates within this band are exceeding 30-40 mm/hr (1.2-1.6 in/hr) with some locations seeing many hours of such rates. The highest storm total thus far seems to have been reported at Mt. Seaview with 593 mm (23.3 in). However, almost all stations in the region have seen at least 300-500 mm. These copious rains over such a widespread area have completely overwhelmed drainage systems.

 

 

 

Streams and rivers are spilling out of their banks and flooding or cutting off entire towns. The Manning River shattered a record level that had stood for almost 100 years. Emergency services have responded to hundreds of car and home rescue calls. Some residents have been forced to retreat to their rooftops to escape the floodwaters. The threat for at least localized heavy rains will continue through Thursday before waning Thursday night. Lead photo courtesy Wikipedia contributor Qumarchi.
