Tropical disturbance threatens Gulf Coast as parts of Louisiana could see a foot of rain or more
According to the National Weather Service, the broad area of low pressure is currently just south of Mississippi and drifting westward, with coastal Louisiana in its projected path.
'This system is forecast to continue moving westward across the northern portion of the Gulf through tonight, reaching the coast of Louisiana by Thursday,' the National Hurricane Center said in its latest forecast.
How much rain could fall?
The current forecast from the National Weather Service office in New Orleans calls for 2 to 4 inches of rain south of Interstate 10 through Saturday, with the potential for up to 8 inches or more in some areas.
'Ponding of water in low lying and poor drainage areas is likely,' the weather service said, with the potential for more significant flooding in low-lying areas 'if the higher end rainfall totals are realized.'
Further west, up to 15 inches of rain is possible in parts of central, south central and southwest Louisiana through Saturday, the NWS office in Lake Charles warned.
What are the chances of it intensifying?
Low. According to the hurricane center, there is a 30% chance that the system will become a tropical depression.
'Some development could occur before the system moves westward into Louisiana later today or tonight, although the chances of the system developing into a tropical depression are low," the hurricane center said. "Regardless of development, heavy rainfall could produce localized flash flooding over portions of the north-central Gulf Coast through Friday.'
How is hurricane season shaping up?
The 2025 Atlantic hurricane season, which began June 1 and runs through the end of November, has gotten off to a relatively slow start.
In May, forecasters at the National Oceanic and Atmospheric Administration predicted there would be 13 to 19 named storms, with six to 10 becoming hurricanes and three to five of those becoming major hurricanes (with winds of more than 110 mph).
A typical hurricane season averages 14 named storms. So far, there have been three: Tropical Storms Andrea, Barry and Chantal.

Hot weather in NYC on Saturday as more storms approach. Here's the First Alert Forecast.
After Friday's heat and strong storms, we're in much better shape weatherwise today in New York, New Jersey and Connecticut. Expect a mix of sun and clouds with temperatures climbing into the mid 80s Saturday. Humidity will be gradually falling, so it will feel close to the actual air temperature. Tonight, clouds increase and there is a chance of a shower or two after midnight. Lows will be in the upper 60s and low 70s. Sunday is our next First Alert Weather Day. There will be plenty of clouds with rounds of showers and storms throughout the day tomorrow. Humidity spikes again, too, so any downpours will be capable of brief heavy rain. Localized spots of flash flooding are certainly possible wherever the heaviest cells move through. Additionally, there is a marginal severe weather risk for the late afternoon and early evening hours. The best chance of some stronger storms will be southwest of New York City. While not a complete washout, try to have alternative plans in place. After sunset, things quiet down before our next round of heat. Heat indices early next week will likely exceed 100 with highs back into the low and mid 90s. Tuesday looks like the day for peak heat. Then, some more storm chances likely move in ahead of a cold front by midweek.

Alert Issued To Millions To Monitor Chest Discomfort
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Air quality alerts have been announced by local authorities, and shared by the federal National Weather Service (NWS), across Vermont and Maine for Saturday due to pollution levels. A separate air quality alert has also been issued for Mesa County in Colorado due to smoke caused by wildfires. Why It Matters According to the NWS sensitive groups, such as children, older people and those with lung or heart disease, may "experience adverse respiratory symptoms" due to the conditions. What To Know The Vermont Agency of Natural Resources (VANR) has issued an air quality alert "for fine particle pollution from wildfire smoke" on Sunday covering Grand Isle, Western Franklin, Orleans, Essex, Western Chittenden, Lamoille, Caledonia, Washington, Western Addison, Orange, Eastern Franklin, Eastern Chittenden and Eastern Addison until 11 p.m. ET in the evening. The state agency says "all individuals should reduce prolonged or heavy exertion" in impacted areas, with those outside urged to "take more breaks and do less intense activities" while also keeping an eye for symptoms such as shortness of breath or coughing. Those with heart disease are urged to contact their health care provider if they experience symptoms such as "palpitations, shortness of breath, or unusual fatigue" which "may indicate a serious problem." Asthma sufferers should keep their medication handy and follow their action plans. A separate VANR air quality alert due to particle pollution in wildfire smoke has been issued until 11 p.m. ET on Saturday for Western Rutland, Eastern Rutland, Western Windsor and Eastern Windsor with the same health advice in place. For these areas the air quality index is expected to "approach or exceed" an unhealthy level for sensitive groups. The VANR has also imposed an air quality alert on Bennington, Western Windham and Eastern Windham until 11 p.m. ET on Saturday due to "fine particulates" which are expected to "approach or exceed the Code Orange or Unhealthy for Sensitive Groups category." Those living in these areas are advised to take the same precautions that were suggested for the previous two alerts. In Maine the Maine Department of Environmental Protection's (MDEP) Bureau of Air Quality has issued an air quality alert related to particle pollution for Southern Penobscot, Interior Hancock, Central Washington, Coastal Hancock and Coastal Washington until 11 p.m. ET on Saturday.

Scott Olson/GETTY The agency advises people to limit strenuous outside physical activity particularly for groups that "may be especially sensitive" such as the elderly and those with respiratory problems. It adds: "If you experience symptoms such as shortness of breath, coughing, throat irritation or an uncomfortable sensation in your chest please consider limiting the intensity and duration of your outdoor activities." The MDEP has also issued an air quality alert until 11 p.m. ET on Saturday for Northern Oxford, Northern Franklin, Central Somerset, Southern Oxford, Southern Franklin, Southern Somerset, Interior York, Central Interior Cumberland, Androscoggin, Kennebec, Interior Waldo, Coastal York, Coastal Cumberland, Sagadahoc, Lincoln, Knox, Coastal Waldo and Interior Cumberland Highlands. Identical health advise has been issued to those in these areas and those covered by the previous MDEP alert with the agency noting: "A plume of smoke moved into Maine overnight bringing much higher particle pollution values than previously expected. As the day progresses, the plume of smoke is expected to keep moving and values should drop down but air quality will continue to be a health concern for much of the day for these regions." Those in Maine can call 1-800-223-1196 poll free to get updates on the air quality situation. Finally an air quality health advisory notice for wildfire and smoke has been issued for Mesa County in Colorado by the Colorado Department of Public Health and Environment until 9 a.m. MTS on Saturday. The agency warns: "If smoke is thick or becomes thick in your neighborhood you may want to remain indoors. This is especially true for those with heart disease, respiratory illnesses, the very young, and older adults. Consider limiting outdoor activity when moderate to heavy smoke is present. Consider relocating temporarily if smoke is present indoors and is making you ill. If visibility is less than 5 miles in smoke in your neighborhood, smoke has reached levels that are unhealthy." In Florida a NWS heat advisory notice is in place for a number of cities on Saturday with the federal agency warning of the danger from "heat-related illness." What People Are Saying For areas impacted by its alert the VANR said: "It's OK to be active outside, but take more breaks and do less intense activities. Watch for symptoms such as coughing or shortness of breath. "People with asthma should follow their asthma action plans and keep quick relief medicine handy. If you have heart disease: symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider." Meanwhile the MDEP said: "The Maine Department of Environmental Protection recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young, the elderly, those with preexisting respiratory problems such as asthma, those with heart disease and anyone who is working hard outdoors. "But if you experience symptoms such as shortness of breath, coughing, throat irritation or an uncomfortable sensation in your chest please consider limiting the intensity and duration of your outdoor activities." What Happens Next Heading into next week a severe heat dome is expected to strike large swathes of the United States with up to 300 temperature records potentially being challenged across the country.
