Typhoon Haikui (2012)

{{storm path|Haikui 2012 track.png}}

At 06:00 UTC on August 1, the Joint Typhoon Warning Center (JTWC) began to monitor an area of convection, associated with a gale-force non-tropical low embedded within the eastern end of a monsoon trough, located approximately {{cvt|550|nmi}} to the north of Guam. At the time, the low had a poorly-defined low-level circulation center, with a large area of deep convection surrounding it, and was under an environment of good equatorial outflow and moderate wind shear.{{Cite JTWC|date=August 1, 2012|time=0600Z|type=abpw|url=http://weather.noaa.gov/pub/data/raw/ab/abpw10.pgtw..txt|archive-url=https://archive.today/20240523061620/https://www.webcitation.org/69c20skq8?url=http://gwydir.demon.co.uk/advisories/ABPW10-PGTW_201208010600.htm|archive-date=May 23, 2024|access-date=November 26, 2023}}{{Cite journal |last=Bancroft |first=George P. |date=April 2013 |editor-last=Rychtar |editor-first=Paula |title=Marine Weather Review – North Pacific Area |url=https://www.vos.noaa.gov/MWL/201304/MWL_0413.pdf |journal=Mariners Weather Log |publisher=National Oceanic and Atmospheric Administration |volume=57 |issue=1 |page=46 |issn=0025-3367 |access-date=November 26, 2023}} Six hours later, the Japan Meteorological Agency (JMA) upgraded the low to a tropical depression.{{cite report|title=WWJP25 RJTD 011200|url=http://weather.noaa.gov/pub/data/raw/ww/wwjp25.rjtd..txt|publisher=Japan Meteorological Agency|date=August 1, 2012|archive-date=August 4, 2012|archive-url=https://archive.today/20120804075020/http://gwydir.demon.co.uk/advisories/WWJP25-RJTD_201208011200.htm|access-date=November 26, 2023}} As the system was developing its center rapidly under increased wind shear, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) late on the same day.{{Cite JTWC|date=August 1, 2012|type=tcfa|designation=99W|url=http://weather.noaa.gov/pub/data/raw/wt/wtpn21.pgtw..txt|archive-url=https://archive.today/20240523061542/https://www.webcitation.org/69c1sAJr6?url=http://weather.noaa.gov/pub/data/raw/wt/wtpn21.pgtw..txt|archive-date=May 23, 2024|access-date=November 27, 2023}} Although it lacked deep convection near its center, the JTWC started issuing advisories on the depression at 21:00 UTC the next day, designating it as 12W.{{Cite JTWC|date=August 2, 2012|type=prog|category=TD|designation=12W|name=Twelve|no=1|url=http://weather.noaa.gov/pub/data/raw/wd/wdpn33.pgtw..txt|archive-url=https://archive.today/20240523061744/https://www.webcitation.org/69f3TrJQP?url=http://gwydir.demon.co.uk/advisories/WDPN33-PGTW_201208022100.htm|archive-date=May 23, 2024|access-date=November 27, 2023}} The JMA subsequently upgraded it to a tropical storm three hours later, naming it as Haikui.{{cite report|title=RSMC Tropical Cyclone Advisory 030000|url=http://weather.noaa.gov/pub/data/raw/wt/wtpq22.rjtd..txt|publisher=Japan Meteorological Agency|date=August 3, 2012|archive-date=August 3, 2012|archive-url=https://archive.today/20120803071421/http://gwydir.demon.co.uk/advisories/WTPQ22-RJTD_201208030000.htm|access-date=November 27, 2023}}

{{further|2012 Luzon southwest monsoon floods}}

Although located hundreds of kilometres away from the Philippines, the southerly flow from Typhoon Haikui enhanced the southwest monsoon across much of Luzon. As a result, widespread heavy rains impacted regions still recovering from deadly floods triggered by Typhoon Saola less than a week earlier. During a 72‑hour span from 6–8 August, {{convert|1007|mm|in|abbr=on}} of rain fell in parts of Metro Manila, leading local media to compare the event to Typhoon Ketsana in 2009, which killed 464 in the city.{{cite news|work=GMA News|date=August 7, 2012|access-date=August 7, 2012|title=Southwest monsoon brings more rains than Ondoy|url=http://www.gmanetwork.com/news/story/268713/news/nation/southwest-monsoon-brings-more-rains-than-ondoy}} Some of the most severe flooding took place along the Marikina River, which swelled to near-record levels.

Numerous schools in Metro Manila, Central Luzon, and Calabarzon had suspended classes. As a precautionary measure, officials cut power to some areas of National Capital Region (NCR). At least 250,000 people left their homes as flooding covered more than a third of the city. The head of the National Disaster Risk Reduction and Management Council (NDRRMC) compared the deluge to the Kevin Costner film Waterworld.{{cite news |url=https://www.nytimes.com/2012/08/08/world/asia/flooding-in-philippines-grows-worse-as-thousands-flee-manila-and-desperate-residents-are-trapped-on-roofs.html |title=Rains Flood Manila Area, Sending Thousands Fleeing |author=Floyd Whaley |date=August 7, 2012 |work=The New York Times |access-date=August 8, 2012}}

Philippine President Benigno Aquino ordered officials to maximize the effort on rescuing and aiding affected residents.

On 8 August, more than 1 million families were already affected. The NCR and nine nearby provinces were already placed under a state of calamity, with some areas were flooded up to 2 storeys. 90 percent of Metro Manila were already submerged in flooding. Communications were affected badly, though distress calls and SMS from thousands of Metro Manila residents and their worried relatives flooded television and radio stations as most power and water connections were lost. Red warning was already downed to yellow during morning but turned back into red warning during afternoon after another set of continuous heavy rain falls again in Metro Manila until midnight of August 9, 2012. Some schools extended their suspension of classes until Saturday. Airports also had severe flooding, forcing some flights to land at Clark International Airport in Pampanga and other airports nationwide or altogether rebooking.{{cite web|url=http://www.abc.net.au/news/2012-08-08/more-than-1-million-battle-philippine-floods/4186366?section=world |title=More than 1 million battle Philippine flood |publisher=ABC News (Australian Broadcasting Corporation) |date=August 8, 2012 |access-date=August 8, 2012}}{{cite news|url=http://www.iol.co.za/dailynews/news/heavy-rains-submerge-manila-1.1358459 |title=Heavy rains submerge Manila |work=Daily News |date=August 8, 2012 |agency=South African Press Association and Associated Press |access-date=August 8, 2012}}{{cite web|author=Chuck Smith |url=http://ph.omg.yahoo.com/news/stars-tweet-for-prayers--help-as-heavy-rains-continue.html |title=Stars tweet for prayers, help as heavy rains continue |publisher=Yahoo!

Slowly moving through the Ryukyu Islands for several days, Haikui brought a prolonged period of heavy rain and high winds to several islands. On Okinawa, sustained winds peaked at {{convert|72|km/h|abbr=on}} and gusts were recorded up to {{convert|122|km/h|mph|abbr=on}}. Rainfall amounted to about {{convert|9|in|mm|abbr=on}}, bringing several dams to full or near-full capacity. No reports of major damage were received on Okinawa, though numerous tree limbs were downed across the island. A total of 353 flights to and from Naha International Airport were canceled, affecting more than 70,000 passengers.{{cite web|author=Dave Ornauer|publisher=Stars and Stripes|date=August 6, 2012|access-date=August 7, 2012|title=Tropical Storm 12W (Haikui), # 11: By the numbers |url=http://www.stripes.com/blogs/pacific-storm-tracker/pacific-storm-tracker-1.106563/tropical-storm-12w-haikui-11-by-the-numbers-1.184969|archive-date=August 9, 2012|archive-url=https://web.archive.org/web/20120809005157/http://www.stripes.com/blogs/pacific-storm-tracker/pacific-storm-tracker-1.106563/tropical-storm-12w-haikui-11-by-the-numbers-1.184969|url-status=dead}}
