Tropical Storm Shanshan, known in the Philippines as Tropical Depression Crising, was a weak tropical cyclone which affected the southern Philippines in mid February 2013. The second named storm of the 2013 Pacific typhoon season, Shanshan developed from a tropical depression on February 18 while located northeast of the Morotai Island. Environmental conditions were marginally favourable that it remained a weak tropical depression while moving west-northwest. The depression struck Mindanao and Palawan on February 19–20, before emerged into the South China Sea. Despite environmental conditions remained marginally favourable, the system briefly achieved tropical storm status late on February 21, and received the name Shanshan. Conditions soon deteriorated, Shanshan weakened back to a tropical depression on the next day and dissipated on February 23.
Although Shanshan remained weak when striking the Philippines, it still brought rainfall and caused flooding and landslides. Provinces across Mindanao and Palawan were placed under PSWS #1. More than 300,000 people were evacuated. Schools were closed in advance of the storm. The NDRRMC reported that 11 people were killed, four were injured and two others were missing, and the damage across the country amounted to Php11.2 million (US$275 thousand).

Shanshan turned southwestward as steered by the northeast monsoon. However, Shanshan only remained as a tropical storm for 18 hours, before weakened back to a tropical depression. Shanshan dissipated early on February 23 just east of the Natuna Islands.
Preparations and impact
Shortly after being classified as tropical depression, the PAGASA issued the PSWS #1 for four provinces in the Davao Region. The PSWS #1 later extended to southern part of Surigao del Sur, Agusan del Sur, provinces in Northern Mindanao, Bangsamoro, Soccsksargen, and Zamboanga Peninsula.{{cite web|url=http://gwydir.demon.co.uk/advisories/TCUPDATE_201302182100.htm|title=Tropical Cyclone Warning: Tropical Depression Crising: Number Three February 18, 2013 21z|publisher=Philippine Atmospheric, Geophysical and Astronomical Services Administration|date=February 18, 2013|access-date=October 1, 2013|archive-url=https://www.webcitation.org/6EXlYle0j?url=http://gwydir.demon.co.uk/advisories/TCUPDATE_201302182100.htm|archive-date=February 19, 2013|url-status=dead}} On February 19, as Shanshan continued to move westward, the PSWS #1 further extended to the Sulu Archipelago and southern Palawan.{{cite web|url=http://gwydir.demon.co.uk/advisories/TCUPDATE_201302190900.htm|title=Tropical Cyclone Warning: Tropical Depression Crising: Number Five February 19, 2013 09z|publisher=Philippine Atmospheric, Geophysical and Astronomical Services Administration|date=February 19, 2013|access-date=October 1, 2013|archive-url=https://www.webcitation.org/6EZGPdVFP?url=http://gwydir.demon.co.uk/advisories/TCUPDATE_201302190900.htm|archive-date=February 20, 2013|url-status=dead}} The PSWS were progressively cancelled as Shanshan began to move away from the Philippines, and all PSWS were canecelled after Shanshan exited the PAR.
Shanshan brought rainfalls to Mindanao, while some areas were still recovering from Bopha which hit the island two months ago. In Baganga, floodwaters were chest-deep. 100 families were evacuated.{{cite news|url=https://www.gmanetwork.com/news/topstories/nation/295802/crising-hits-pablo-affected-areas-1-dead-thousands-evacuated-due-to-floods/story/|title=Crising hits Pablo-affected areas; 1 dead, thousands evacuated due to floods|publisher=GMA Network|date=February 20, 2013|access-date=October 1, 2013}} Dipolog experienced minor flooding, but the rest of the Zamboanga Peninsula didn't felt much impacts. In Jose Abad Santos, Davao Occidental, Shanshan brought minor showers, though no one was injured in the city. Pre-school classes were suspended in Davao City on February 19, as PSWS #1 were issued.{{cite news|last=Aguirre-Tuburan|first=Marilou|url=https://davaotoday.com/environment/davao-suspends-pre-school-classes-as-pagasa-raises-storm-signal-1-with-crising/|title=Davao suspends pre-school classes as Pagasa raises Storm Signal 1 with "Crising"|publisher=Davao Today|date=February 18, 2013|access-date=June 5, 2023|archive-url=https://web.archive.org/web/20230606015648/https://davaotoday.com/environment/davao-suspends-pre-school-classes-as-pagasa-raises-storm-signal-1-with-crising/|archive-date=June 6, 2023|url-status=live}} Schools in Cebu City, Lapu-Lapu City, and Talisay were closed on February 20 due to Shanshan,{{cite news|url=http://www.sunstar.com.ph/network/local-news/2013/02/20/3-cebu-cities-suspend-classes-269167|title=3 Cebu cities suspend classes|publisher=SunStar|date=February 20, 2013|access-date=October 1, 2013|archive-url=https://web.archive.org/web/20130507131002/http://www.sunstar.com.ph/network/local-news/2013/02/20/3-cebu-cities-suspend-classes-269167|archive-date=May 7, 2013|url-status=dead}} but no flooding and landslides reported in the province.{{cite news|last=Chua|first=Vince Harlan A.|url=https://www.sunstar.com.ph/more-articles/no-floods-from-crisings-rain|title=No floods from Crising's rain|publisher=SunStar|date=February 20, 2013|access-date=October 1, 2013}} Heavy rains triggered flooding and landslides in Mindanao and Eastern Visayas, four people were killed and two were missing.{{cite news|url=https://www.rappler.com/philippines/22382-tropical-depression-crising-leaves-4-dead-2-missing/|title=Crising leaves 4 dead, 2 missing|publisher=Rappler|date=February 22, 2013|access-date=October 1, 2013|url-access=registration}} According to the National Disaster Risk Reduction and Management Council (NDRRMC), a total of 360,577 people were affected, 85% of the affected population were evacuated to temporary shelters.
