Thunderstorms over the central and eastern parts of the nation will bring severe weather and a flooding threat on Monday. In addition, potential hurricanes are brewing in the Atlantic, plus storms over the South and East on Tuesday. See the three-day forecast now.
Here are Monday’s weather alerts from the National Weather Service (NWS).
Flood warning: central and southeastern Mississippi, southeastern Louisiana, northern Texas, and northwestern South Dakota.
Flood watch: southeastern New Mexico, western Texas, northeast Florida, and southeast Georgia.
Excessive heat watch: central and southern California, southern Nevada, and western and central Arizona.
Heat advisory: western New York.
It has been a quiet two months in the tropics, but activity in the Atlantic is ramping up. Americans are urged to review and make hurricane preparations.
Forecasters with the National Hurricane Center (NHC) are watching four areas of disturbed weather in the Atlantic. Attention is focused on “Disturbance 1,” also named “Invest 91L,” which has an 80% chance of development within the next five days and a 50% chance in the next two days. The system will be tracking just northwest of the Leeward Islands by the end of the week, and most forecast models have the storm turning back to sea, WPTV reported.
Three other systems are of potential concern: “Disturbance 2” has a 10% chance of cyclone development, “Disturbance 3” has a 30% chance of development, and “Disturbance 4,” located east of Belize and Cancún, has a 20% chance of development over the next five days, according to the NHC.
Thunderstorms over nearly half the nation to start the week, predominantly over the Southwest, South, and East on Tuesday. Storms are diminishing on Wednesday except over parts of the South and Northeast.
