Beryl Brings Heavy Rain and Flash Flood
Now a tropical rainstorm, Beryl will continue to impact regions well beyond Texas through the middle of next week, bringing with it tornadoes, flash flooding, and a lot of rain to the Northeast and Central states. Tropical downpours will continue along the Eastern Seaboard after Beryl moves on, increasing the possibility of flash flooding and possibly relieving the drought and heat in certain areas.
When Beryl first touched down in Texas on Monday, it brought with it severe thunderstorms, flooding, high winds, and a lot of rain. Because of a tiny dip in the jet stream, Hurricane Beryl is traveling more quickly than Hurricane Harvey, which stalled over Texas in August 2017 and caused catastrophic flooding. This quick movement won’t stop severe rain and flooding, though, all the way to New England.
For former hurricanes and tropical storms, US meteorologists refer to them as “tropical rainstorms” to highlight the possibility of hazards and disruptions long after the National Hurricane Center discontinues designating the systems. Beryl is and will remain one of these systems.
Beryl’s intense rain is expected to move northeast from Arkansas by Monday night and reach the Lower Peninsula of Michigan and northwest Ohio by Tuesday night. In these regions, 2-4 inches of rain is expected on average, with isolated reports of 4–8 inches, especially from Arkansas to northwest Indiana. It might rain almost 12 inches in some places.
Due to Beryl’s rain and rising secondary tributary rivers in Missouri and Illinois, a surge of high water will move south along the middle Mississippi River. As a result, water levels may rise more and last longer. Beryl’s core is expected to move through the St. Lawrence Valley, which borders both the United States and Canada, upstate New York, and the eastern Great Lakes by midweek.
According to US Meteorologist, Beryl will interact with non-tropical systems and additional moisture from the Atlantic as it moves into the Northeast, probably resulting in more widespread downpours and strong thunderstorms than Beryl alone.
A significant area of high pressure off the East Coast will bring in moisture along the Atlantic Seaboard to the Appalachians from midweek to Friday, with the possibility of it continuing into Saturday, and cause a heatwave through midweek. Massive downpours brought on by this moisture may help some regions that are suffering from drought while causing flash flooding in other areas.
Beryl is expected to bring heavy rains to parts of northern New England, starting on Wednesday and continuing through Wednesday night. By midweek, another round of rain is expected to develop along the mid-Atlantic coast and spread into New England. Remaining moisture will bring more showers and thunderstorms from Thursday to Friday, possibly continuing into Saturday along portions of the Atlantic Seaboard, even after Beryl’s core moves on.
Any Atlantic disturbance has the potential to increase this moisture, producing isolated areas of heavy rain.
Beryl and the moisture from the Atlantic could bring up to half a foot of rain or more to parts of the East from Wednesday to Saturday. According to US Senior Meteorologist, some regions, including the Ohio Valley, southwest Pennsylvania, and northern West Virginia, may receive little to no rain from this rain, despite the possibility of dangerous flash flooding.
Beryl threatens tornadoes in the central and northeastern United States in addition to intense rain and flash flooding. As Beryl moved inland on Sunday night and into Monday, it prompted multiple tornado warnings along the Texas coast.
Tornadoes can form quickly when a combination of dry air, tropical moisture, and storm rotation occurs.
According to Forecasters, some tropical systems, like Beryl, have the ability to produce tornadoes far from their landfall area. The energy of the jet stream may increase this risk in the vicinity of the Northeast and Great Lakes. While Beryl passes through the middle Mississippi Valley and the Great Lakes region, there will still be a chance of severe weather, including tornadoes, to the southeast and near its center.
The areas with the highest risk of severe thunderstorms and tornadoes on Tuesday and Tuesday night are southwestern Ohio, southern Illinois, southern Indiana, western and northern Kentucky, and northeastern Arkansas and western Tennessee.
From Wednesday to Wednesday night, the risk will extend from eastern Ohio to much of Pennsylvania, northern West Virginia, western and central Maryland, southern and eastern New York, northern New Jersey, and southwestern New England.
Beryl, a tropical rainstorm, will impact regions far beyond Texas through midweek. It will bring heavy rain, flash flooding, and tornadoes to the Central states and the Northeast. As Beryl moves, torrential rains and severe weather will persist along the Eastern Seaboard, potentially easing drought and heat in some areas. The storm’s progression will be influenced by various atmospheric conditions, leading to widespread rainfall and potential severe weather.
