Post-Tropical Cyclone Beta will continue to bring heavy rainfall and flooding to parts of Texas and Louisiana, with areas of rainfall also gradually spreading across the Southeast. Elsewhere, Hurricane Teddy will remain in the Atlantic, but bring dangerous rip currents, high surf, and swells to much of the East Coast. A low pressure system in the northeastern Pacific will bring rainfall to the Northwest by Wednesday. States with Active Advisories: Texas, Louisiana, Massachusetts, Maine

• Texas - Upper Coast: 3-5 inches additional rainfall, up to 15 inches through this afternoon
• Lower Mississippi Valley: 2-5 inches of rainfall through end of week
• Tennessee Valley: 2-5 inches of rainfall through end of week
• Southern Appalachians: 2-5 inches of rainfall through end of week

Tropical Storm Beta made landfall around 10 p.m. CDT last night along the Matagorda Peninsula.  Beta is forecast to move very slowly, or even stall, just inland from the middle Texas coast on Tuesday and Tuesday night, continuing to bring heavy rainfall and flooding to parts of Texas and Louisiana. Meanwhile, Hurricane Teddy will remain in the Atlantic but bring dangerous rip currents, high surf, and swells to much of the East Coast. A low pressure system in the northeastern Pacific will bring rainfall to the Northwest by Wednesday. States with Active Advisories: Texas, Louisiana

While currently stalled just inland of the Texas coast, Beta should begin to move by Wednesday on a more northeastward track near or just inland from the upper Texas coast as it weakens to a tropical depression. Beta should become a remnant low by Thursday as it moves into the lower Mississippi Valley.  Portions of I-45, I-69, and I-610 are closed and/or flooded on the southern side of Houston. 

Flooding Rainfall

• Houston Metro:  6 to 10 inches of rainfall, with locally up to 20 inches
• ArkLaTex Region:  3 to 5 inches of rainfall
• Lower Mississippi Valley: 3 to 5 inches of rainfall

Flash flood watches have been issued by the National Weather Service from the middle Texas coast to southeast Louisiana, including Houston, Lake Charles and New Orleans.

Storm Surge
Surge Flooding will continue throughout the morning along the Texas coast within warning areas

Tropical-Storm-Force Winds
High winds will continue near portions of the Texas coast within the warning area today from Port Aransas, Texas, to Sabine Pass, Texas. The strongest winds will be in the offshore waters.

Tornadoes
A few tornadoes are also possible on the middle and upper Texas Coast and in southwest Louisiana through Tuesday.

Summary - Tropical Storm Beta is centered just over 100 miles south of Galveston, Texas, and is moving westward towards the Texas coast at little over 5 mph. The expected slow motion of Beta will produce a long duration rainfall event, bringing the risk of storm surge and flooding from the middle Texas coast to southeast Louisiana. Meanwhile, Hurricane Teddy will remain in the Atlantic but bring swells, dangerous surf, and rip currents to much of the east coast. States with Active Advisories: Texas, Louisiana

After landfall, Beta will drift northeastward on the Texas coast Monday night through Wednesday.

Heavy rainfall, flooding, gusty winds, and the risk of a few tornadoes will continue over portions of the Southeast U.S. as Tropical Storm Sally gradually weakens. States with Active Advisories: Georgia, South Carolina, North  Carolina, Virginia

The center of Sally is about 50 miles southeast of Montgomery, Alabama. Sally is picking up forward speed and is weakening as it moves inland over the Deep South. Flooding rainfall and gusty winds continue to impact parts of Georgia and is spreading into the Carolinas.  Widespread flooding is expected from central Georgia through southeastern Virginia. Along the central Gulf Coast, most widespread moderate to major river flooding form the historic rainfall event will crest by the weekend, but rivers will remain elevated well into next week.

Hurricane Sally made landfall near Gulf Shores, Alabama at at 4:45 a.m. CDT as a Category 2 with maximum sustained winds of 105 mph.  Sally continues to move slowly north-northeastward into the coastline, with the slow movement bringing prolonged impacts to the Gulf Coast, including catastrophic flooding to portions of Florida and Alabama today along with damaging winds and the risk of tornadoes. Heavy rainfall will also advance north and east into Georgia and the western Carolinas. The storm will weaken quickly and pick up forward speed as it tracks inland across Alabama and Georgia later today through Thursday. States with Active Advisories: Mississippi, Alabama, Georgia, Florida

Hurricane Sally is moving near the coast of southeastern Louisiana and hurricane conditions are expected early Tuesday. Sally is expected to be a dangerous hurricane when it moves onshore along the north-central Gulf coast. Multiple impacts are expected with this system: extremely dangerous and life-threatening storm surge, hurricane-force winds, torrential rain with flash flooding and possible tornadoes. Sally will likely make landfall on Tuesday or Tuesday night with sustained winds of at least 110mph making it a strong and dangerous Category 2 storm. States with Active Advisories: Louisiana, Mississippi, Alabama, Florida

• 6 to 9 feet from Ocean Springs, Mississippi, to Dauphin Island, Alabama, including Mobile Bay.
• 4 to 7 feet from Dauphin Island, Alabama, to the Florida border and from the mouth of the Mississippi River in Louisiana to Ocean Springs, Mississippi, including Lake Borgne.

• 10 to 20 inches with locally up to 30 inches on the Gulf Coast from the western Florida Panhandle to southern Alabama and far southeastern Mississippi through Wednesday. Serious flash flooding and moderate to major river flooding could occur in these areas.
• 4 to 8 inches, with locally up to 12 inches, is possible farther inland across southeastern Mississippi, southern and central Alabama, northern Georgia and the western Carolinas. Significant flash and urban flooding is likely, as well as widespread minor to moderate flooding on some rivers in these areas.

• East of the mouth of the Pearl River, Mississippi, to Navarre, Florida, including Biloxi, Mobile and Pensacola.
• Hurricane conditions (winds 74 mph or greater) are expected in some parts of this area late Tuesday into Wednesday.

Tropical Storm Sally is forecast to become a Hurricane on Monday while approaching the northern Gulf Coast. Sally will bring hurricane conditions including strong winds, extremely dangerous and life-threatening surge, heavy rainfall with widespread significant flash flooding, isolated tornadoes and swells that are likely to cause life-threatening surf and rip current conditions. While it is too early to determine exactly where the storm center will move onshore, Sally's slow movement will result in prolonged impacts along the Gulf Coast. States with Active Advisories: Louisiana, Mississippi, Alabama, Florida

Sally is centered over 100 miles east-southeast of southeast Louisiana. The storm is lopsided right now with much of its rain and thunderstorm activity off to the east of its center. Bands of rain and gusty winds will be on the increase in parts of the northern Gulf Coast through the day on Monday.

Dangerous Storm Surge conditions are expected from Port Fourchon LA to the Alabama/Florida border. Hurricane conditions are expected later today from Morgan City, LA to the Mississippi/Alabama border, including New Orleans. Flash flooding is expected across central and northern FL, with flooding likely across southeast LA, MS, and AL before spreading farther across the Southeast U.S. later this week. 

Wintry weather in the Rockies and Plains will gradually decrease. Heavy rain and flash flooding will be possible for central Texas, and portions of the East Coast. In addition, a couple of tropical disturbances off the Southeast coast and Florida warrant watching. States Active Advisories: Colorado, New Mexico
