50 million people are under flood warnings, advisories, and watches in the Northeast, while the West is sizzling and facing an electrical grid emergency. Four systems are active in the Atlantic. Weather alerts and the 3-day forecast.
Here are the latest weather alerts for Tuesday from the National Weather Service (NWS).
Flood warnings, advisories, and watches for portions of Maryland, Delaware, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, and Massachusetts.
Excessive heat warning: most of California; southern and northeastern Nevada; southern Utah; northern, western, central, and southwestern Arizona.
Heat advisory: southwestern, central, and eastern Oregon; central and southern Idaho; northern and northeastern California; central and northern Nevada; western, central, and south-central Utah.
Red flag alert: central, northern and eastern Washington; Montana; northern Idaho; most of Oregon; northeastern California; north-central Wyoming; northwestern South Dakota.
Four systems are currently active systems in the Atlantic: a hurricane, a tropical storm, and two disturbances.
Hurricane Danielle has maximum sustained winds of 75 miles per hour and is expected to weaken over the next several days and have no impact on the US, WFLA reported.
Tropical Storm Earl has maximum sustained winds of 65 mph with tropical storm-force winds extending outward up to 115 miles from the storm’s center. No threat yet but could potentially move toward Bermuda.
“Disturbance 1” has a 60% chance of cyclone formation in the next 5 days and track into the center of the Atlantic, and “Disturbance 2,” is located off the coast of West Africa with a 20% chance of cyclone formation in the next 5 days, according to the National Hurricane Center (NHC).
Major flood threat to at least a dozen states in the Northeast on Tuesday, while a massive heatwave over most of the Western states could stress California’s electrical grid and lead to outages. Storms will diminish heading into midweek for the majority of the Lower 48.
Here is the latest 3-day forecast from the National Weather Service (NWS).
Thunderstorms will extend from Texas, over the South and Southeast, and northward over much of the mid-South, Ohio Valley, mid-Atlantic, and Northeast. An estimated 50 million people in the mid-Atlantic and Northeast will be under the threat of flooding (see alerts above). Flooding will also be possible for parts of Vermont, New Hampshire, and Maine.
At least 10 states in the West will experience scorching temperatures (see alerts above). California is predicted to reach a record-setting electricity demand, which could prompt the California Independent System Operator (California ISO) Warren to declare a grid emergency for the 6th straight day and lead to “rolling outages,” Zero Hedge reported.
Heat to continue in the West and scattered thunderstorms in the Northwest will bring more red flag alerts over Montana.
Scattered thunderstorms over Texas, the South, Southeast into portions of the mid-Atlantic and Northeast.
Fewer storms than earlier in the week, with scattered thunderstorms over the northern tier and portions of Montana, Wyoming, the Dakotas, Minnesota, and Wisconsin. To the south, storms mostly along the Gulf over parts of the South and Southeast.
Mostly clear for much of the West, central US, Midsouth, Ohio Valley, mid-Atlantic, and Northeast.
