Eastern Bangkok still has standing water in sois; main roads are reopening

What happened: Bangkok · Oct 4 · As of Friday, October 2, the BMA said most main roads in the flood-hit east are passable again, including Chaloem Phrakiat Rama IX, Suwinthawong, Krungthep Kreetha and Phatthanakan roads. Water is still standing in sois and housing communities in Lat Krabang (notably Rom Klao), Saphan Sung, Bang Kapi (Khlong Chan) and Min Buri, including along Rat Phatthana Road and under the motorway on Srinakarin Road. Governor Chadchart Sittipunt said the priority is pumping water out through the Prawet Burirom canal, which is still high and is slowing drainage from Lat Krabang.
Why it matters: A main road being open doesn't mean the side streets are dry. Water in parts of Lat Krabang is draining slowly because the canals it drains into are still full, and heavy rain is forecast for October 5–6.
Who it affects: Residents of Lat Krabang, Saphan Sung, Bang Kapi and Min Buri, and anyone commuting to Suvarnabhumi or the eastern suburbs by road.
What you should do: Check your own soi, not just the main road, before heading out by car or motorbike. Avoid wading through standing water. To report flooding or ask for help, call the BMA hotline 1555 or use LINE @TraffyFondue.

Heavy rain forecast for Bangkok October 5–6, with more storms likely mid-month

What happened: Bangkok · Oct 4 · The Thai Meteorological Department (TMD) issued warning No. 4 at 5am on Saturday, October 3. It forecasts heavy to very heavy rain, thunderstorms and gusty winds across much of Thailand from October 4 to 7. Bangkok and surrounding provinces are expected to be hit hardest on October 5 and 6, with a risk of flash floods and run-off in low-lying areas. Separately, the Hydro-Informatics Institute flagged heavy-rain risk on October 3 for eight eastern districts (Watthana, Bang Kapi, Suan Luang, Bueng Kum, Khan Na Yao, Wang Thonglang, Saphan Sung and Prawet) and on October 4 for Bang Sue, Chatuchak, Dusit, Phaya Thai and Din Daeng. The Royal Irrigation Department expects a short break on October 8–9 and more heavy rain across the Central region on October 11–14.
Why it matters: The main flood risk to Bangkok this week is heavy local rain overwhelming street drains, not the Chao Phraya River. Parts of eastern Bangkok are still draining from last week's floods, so they will flood again faster than other areas.
Who it affects: Everyone in Bangkok, especially people living in or commuting through the eastern districts (Lat Krabang, Bang Kapi, Saphan Sung, Min Buri, Prawet, Suan Luang) and anyone with plans or travel on October 5–6.
What you should do: Plan errands and travel around October 5–6 and leave extra time. Keep valuables, documents and electrical items off the floor if you live in a low-lying area. Avoid walking through floodwater. Flood or blocked-drain reports: BMA hotline 1555 or LINE @TraffyFondue. TMD weather hotline: 1182. TMD updates its warnings several times a day at tmd.go.th.

Thai Airways back to a full schedule; unclaimed bags go to the airline

What happened: Bangkok · Oct 4 · Thai Airways said it would run all scheduled flights from Saturday, October 3, after cutting 15 flights on October 1 and 9 on October 2 because of a staff shortage. More than 10,000 bags piled up at Suvarnabhumi after flooding kept airline staff from getting to work from September 26. With help from Royal Thai Air Force and Army personnel, the airport aimed to return the remaining bags by October 3, with a final clearance deadline of Sunday, October 4. Bags still unclaimed after that are handed to Thai Airways for safekeeping. Passengers can collect bags at Suvarnabhumi or have them sent by Thailand Post. The airline's board removed CEO Chai Eamsiri on October 2.
Why it matters: Flying out of Suvarnabhumi on Thai Airways should be close to normal now. The airline expects to be back to its usual 115 flights a day within about a week. If your bag still hasn't arrived, after October 4 it's the airline you deal with, not the airport.
Who it affects: Anyone who flew Thai Airways through Suvarnabhumi between September 26 and October 2 and is still missing a bag, and anyone flying Thai Airways in the next week.
What you should do: If you're missing a bag, contact Thai Airways directly and keep your baggage tag and boarding pass. The airline's ticket office at its Vibhavadi Rangsit Road headquarters is open 8am–5pm on October 3–4. Check your flight status before going to the airport this week.

Chao Phraya flow into Bangkok stays well below flood-wall limits

What happened: Bangkok · Oct 4 · On Saturday, October 3, the Royal Irrigation Department (RID) said river flow just upstream of Bangkok (station C.29B) was 2,382 cubic meters per second, below the 3,600 the city's flood walls are built to handle. The Chao Phraya Dam is releasing about 2,500 cubic meters per second, and flow further north at Nakhon Sawan has started to fall now that the peak has passed. A Rangsit University flood expert, Seree Supratid, said on October 2 that his most likely scenario shows virtually no river-flood risk to inner Bangkok, though Nonthaburi, northern Pathum Thani and low-lying Ayutthaya remain exposed.
Why it matters: Many people fear a repeat of 2011. This year's river volume is far smaller: about 4.3 billion cubic meters has passed Nakhon Sawan, against 15 billion in 2011. Inside Bangkok's flood walls, the risk this week is heavy rain on the streets, not the river. Areas outside the walls along the river can still flood at high tide.
Who it affects: People living along the Chao Phraya, especially outside the flood walls and in Nonthaburi and Pathum Thani, and anyone worried about a 2011-style flood.
What you should do: If you live right on the river outside the flood walls, keep belongings raised during the late-afternoon high tides. Otherwise, no river-related action is needed in central Bangkok. Watch the rain forecast for October 5–6 instead.

Been in floodwater? Watch for leptospirosis symptoms for up to two weeks

What happened: Bangkok · Oct 4 · The Department of Disease Control (DDC) warned on September 28 about leptospirosis as flooding continues. The bacterial infection spreads through floodwater or mud contaminated with animal urine, mostly from rats, and gets in through cuts or soaked skin. Thailand recorded 3,303 cases and 46 deaths from January 1 to September 23, 2026. Symptoms usually appear one to two weeks after contact: high fever, headache, muscle pain (especially in the calves or thighs), nausea, vomiting, diarrhea and red eyes.
Why it matters: Symptoms can start a week or two after the water has gone, when people no longer connect them with the flood. It's treatable with antibiotics if caught early, and can be fatal if not. Preventive antibiotics are mainly for high-risk people such as rescue workers in water for hours. People who only waded briefly generally don't need them.
Who it affects: Anyone who waded through floodwater or cleaned up flood mud in the past two weeks, especially with cuts on their feet or legs.
What you should do: If you develop a fever or the symptoms above after contact with floodwater or mud, see a doctor promptly and tell them about the exposure. Wear boots and gloves for cleanup, wash with soap and water right after, and cover any cuts. Empty standing water from pots and buckets around your home to cut down dengue mosquitoes. DDC hotline: 1422.

Nominee crackdown: details of 100,000+ foreign-linked firms sent to 43 embassies

What happened: Bangkok · Oct 4 · The Department of Business Development (DBD) said around September 30 that it has sent details of more than 100,000 foreign-linked Thai companies, covering 48 nationalities, to 43 foreign embassies as part of its crackdown on nominee shareholdings, where Thais hold shares on behalf of foreigners to get around the Foreign Business Act. Its screening found about 2,100 firms with structures suggesting nominee links and 10,000 more under review. Foreign-invested firms in the screening hold more than 305,000 land plots. Director-General Poonpong Naiyanapakorn said legitimate foreign investors remain welcome. What the embassies are expected to do with the data hasn't been explained.
Why it matters: Being on the list is not an accusation of wrongdoing. But nominee arrangements are illegal: Thai nominees and foreigners running restricted businesses can face up to three years in prison and fines of 100,000 to 1 million baht. Scrutiny now includes land, shareholder funds and money trails.
Who it affects: Foreigners who own or run a Thai company, or hold land or a house through a Thai company or Thai shareholders.
What you should do: If your business or property is held through a Thai company with Thai shareholders, check with an independent Thai lawyer that the structure is lawful, and keep records showing where shareholders' capital came from. Be wary of anyone offering to 'fix' your company for a fee who isn't a licensed lawyer.

New national disaster insurance started October 1, tied to Thai house registration

What happened: Bangkok · Oct 4 · A government-funded disaster insurance scheme took effect at 12:01am on October 1, covering about 30 million homes nationwide against floods, windstorms and earthquakes. Cabinet approved about 15.5 billion baht for it on September 22, and 11 insurers have joined. Homes are enrolled automatically through the Thai house registration system (tabien baan), so owners don't apply or pay. Reported payouts start at 10,000 baht for flood damage. The Department of Disaster Prevention and Mitigation and the Office of Insurance Commission say they will publish a claims manual. Prime Minister Anutin Charnvirakul said flooding before October 1, including last week's Bangkok floods, falls under the existing relief rules instead (including a 9,000-baht payment).
Why it matters: The scheme doesn't cover last week's floods. Because it runs on Thai house registration and Thai ID-linked payments, it's unclear whether foreign residents or renters can claim. It doesn't replace your own home or contents insurance.
Who it affects: Foreign residents who own or rent homes in Thailand, and anyone affected by future floods or storms.
What you should do: Don't count on this scheme if you're a foreigner or a renter. Check whether your own contents or condo insurance covers flood damage. If your home is registered in your or a Thai partner's name, ask your district office how claims will work once the manual is out. For last week's flood damage in Bangkok, use the BMA flood aid process instead.

Immigration's THIM app now handles the digital arrival card (TDAC)

What happened: Bangkok · Oct 4 · The Immigration Bureau has launched THIM (Thailand Immigration Management System), a free app on the App Store, Google Play and Huawei AppGallery. For now it does two things: lets foreigners fill in the Thailand Digital Arrival Card (TDAC), and an 'Explore Thailand' section with travel information and partner discounts. You build a profile once by scanning your passport, then only update details like your flight on later trips. The bureau says this cuts the arrival card to about three minutes, and officers see your data when they scan your passport, so there's no QR code to show. The bureau says future versions will add immigration-office queue booking, visa extensions, 90-day reporting and certificates of stay. It reports more than 600,000 downloads so far.
Why it matters: The TDAC is still required for every foreign arrival. THIM is just another way to submit it; the Immigration Bureau website still works. 90-day reports and extensions can't be done in the app yet, despite what some posts suggest.
Who it affects: Anyone flying into Thailand, including residents returning from trips, and long-stay residents who'll want to watch for 90-day reporting and extensions in the app later.
What you should do: Submit your TDAC through the official THIM app or the Immigration Bureau's TDAC website. Both are free. Ignore sites that charge a fee for the TDAC. Download THIM only from the official app stores. Immigration hotline: 1178.

Vegetarian Festival runs October 10–18; Chinatown fills with yellow-flag food stalls

What happened: Bangkok · Oct 4 · Thailand's annual Vegetarian Festival (Nine Emperor Gods festival) runs October 10 to 18 this year. In Bangkok, the center is Yaowarat (Chinatown), where stalls flying yellow flags marked 'jay' sell plant-based food made without meat, dairy, garlic or onions. Phuket hosts the best-known processions; Trang, Krabi and Chiang Mai also celebrate.
Why it matters: It's one of the easiest weeks of the year to eat fully plant-based in Bangkok, and many ordinary restaurants and convenience stores add jay menus. Yaowarat gets very crowded, especially in the evenings.
Who it affects: Anyone who eats plant-based, or wants a Chinatown night out in mid-October.
What you should do: Look for the yellow flags with red lettering, which mark jay food. Go early in the evening or on a weekday to avoid the biggest crowds, and take the MRT to Wat Mangkon station rather than driving. If heavy rain returns, check the forecast before heading out.
