Flash floods in Quezon City
The rains poured again this afternoon and it was quite intense for more than an hour in Quezon City. We had floods at the UP campus and along Katipunan Avenue. Reports from various sources stated that there were also floods along EDSA and other major roads in the city. The floods come at a time when QC flagged flood control projects undertaken by the DPWH without the city’s blessings.
The flash floods were probably proof of the shoddy work associated with DPWH and its contractors. While QC residents and the LGU should share the blame for these, the scale and frequency of the floods indicate drainage issues.
The floods have led to intense traffic congestion and commuters being stranded due to public transport vehicles not being able to turn around. The latter is one of the cases where public transport appears to be lacking. Their numbers may not be lacking at all but the traffic conditions prevent their turnaround to address the demand for transport.

Shoes for the wet season
I wrote about how a pair of shoes didn’t last long particularly for my daily walking. This time, I’m featuring a pair from a brand that I’ve been patronizing for more than 2 decades now – Merrell.
Their shoes have been very dependable and I’ve had 5 pairs over the more than 2 decades I’ve used them. That’s about 4 years per pair even considering my shoe rotation (I also have other shoes, of course. ) I would say that they’re better than the Adidas Terrex shoes I’ve had and perhaps at par with the GT Hawkins I had when I was a student in Japan. I hope the quality is maintained for these durable shoes that is my preferred pair for the wet season.

Pothole season
The heavy rains the past days have taken a toll on many roads. Special mention here would be city roads such as main arterials where traffic flow is affected by the pavement conditions. Here are a couple of photos of potholes along Katipunan Avenue.
The photos also reveal that cement concrete slabs are actually under the asphalt concrete. This means asphalt concrete was used more as an overlay to protect the cement concrete slab rather than as the main structural component that will carry the traffic loads. The pavement slabs may not necessarily be compromised but the hammering action of tires/wheels as they hit the potholes will definitely lead to more damage. The water, of course, is worrisome because once they seep or penetrate the cracks and interfaces between the slabs, they may compromise the layers beneath the slab. This will weaken the foundation of the pavement and lead to more critical damage. The challenge is how to repair these potholes when we are still experiencing heavy rains. Now that’s something the DPWH needs to figure out, learn and apply rather than the usual patch up work that results in mounds of asphalt replacing the potholes.

Here comes the rain again…
And just like that, Habagat is here and dumping rains upon us again. Yesterday’s downpour during the early afternoon resulted in flash floods including a few along our route home.
The combination of heavy rains and floods have significant impacts on transportation as traffic slows down or even stops as roads become impassable. As most commuters are dependent on road based transport, this means a tremendous inconvenience to a lot of people.
I’ve also written about this topic before. Despite the implementation of various flood control and drainage improvement projects, we seem to be back to square one once the rains come. There is certainly something wrong that the floods are still here after spending so much to mitigate them.

Foggy roads – Part 2
This is supposed to be a follow-up to the post on foggy roads in Tagaytay last month. Unfortunately, I could other things came in the way of finishing this Part 2. Intersections can be quite dangerous if all approaching one have limited visibility. Add to that the flaws in intersection geometry that may contribute to it being risky to travelers. Following is an example along the Tagaytay-Calamba Road with an intersection with Belleview Drive, which is the main access road to Tagaytay Highlands.
The approach from Tagaytay features a curve. I didn’t notice any streetlights along the road so I can imagine it must be poorly lit at night. What more if there is a thick fog in the area?
The bike lane is a product of the government’s efforts to come up with a bike lane network along national roads during the pandemic. This is actually the shoulder painted to become a bike lane. This is the view of the intersection approach if you’re coming from Tagaytay. The leg to the right with the people with umbrellas is Belleview Drive and towards Tagaytay Highlands. You can easily miss this if you were not familiar with the area and cruising along the highway. Note the thick fog obscuring your vision of the intersection. The curvature to the left also adds to the complex situation.
This is a closer look at the highway approach from Tagaytay taken a few minutes after I took the first photo in the article. Note the fog quickly setting in and the limited visibility. The motorcycle moving away from us would disappear into the fog. This is during the daytime and supposedly in broad daylight. Vehicles would need to turn on their lights so others may see them on the road.
The sign along Belleview Drive states the obvious. There should be more signs like this located strategically along the Tagaytay – Calamba Road and others usually cloaked in the fog we experienced in Tagaytay recently.I assume there would be similar situations elsewhere including in Baguio City. We also experienced fog (not smog) in Antipolo but these were quick to dissipate unlike the ones in Tagaytay and Baguio.

On the impact of more frequent lightning strikes on airports
We were waiting for our plane to arrive at the airport yesterday and can’t help but observe the heavy rains falling while a strong wind blows and causes the rains to fall at an angle. This renders umbrellas to be ineffective in keeping you dry if you’re outdoors. Such weather requires a long coat or even overalls to keep one dry on a very wet day. The rains and wind were brought about by a storm affecting the area. Though distant, the storm was able to influence the weather. Fortunately, there wasn’t any lightning and we wondered if lightning strikes have affected ground crew working in an open area that makes them vulnerable to lightning strikes. Here is an interesting article that describes the threat of lightning strikes particularly to people on the ground at airports.
King, R.E. (September 11, 2024) “Increasing Lightning Strikes from Stronger Storms Could Cripple Airports and Airbases,” Jalopnik, https://jalopnik.com/increasing-lightning-strikes-from-stronger-storms-could-1851645799 [Last accessed: 9/16/2024]
Quoting from the article:
“While flying planes are hardened to withstand lightning strikes, airports are typically a cluster of free-standing structures on a flat, open plot of land. The ongoing increase in lightning strikes caused by climate change is a direct danger to facilities and people on the ground.”
I wonder about similar data or statistics in the Philippines considering the long wet season we have that includes not just threats from typhoons but from seemingly small weather systems that may involve lightning strikes. I recall operations at NAIA were halted a few times when there were lightning storms. Is this phenomena. I wonder how many incidents at our airports have been reported and recorded pertaining to lightning.

Foggy roads in Tagaytay – Part 1
It’s been a while since the last time I was in Tagaytay. We used to go there at least once a month. Eventually, we grew tired of the traffic and the city becoming quite crowded. Of course, our schedules also became more busy so the drives for a weekend getaway turned into trips for music lessons (for our daughter) and meet-ups with friends. It was a welcome return last July when I had to go to Tagaytay Highlands for a meeting and then join up with our college for a workshop on the other end of the city. Here are some photos of the foggy roads that reminded me of the Tagaytay of old.
More photos of the foggy roads in the next post!

On transportation and floods
Some people say transport and traffic concerns take a backseat to floods and related concerns, which affect other aspects of our lives aside from our commutes. The heavy rains the past days have rendered many streets impassable to most types of vehicles. That means people cannot go to work, school or come home. Lives are disrupted by floods this way. But even more disruptive and disastrous are the damages brought about by flooding in many communities. Homes are submerged. Properties are damaged, many beyond repair or replacement. There is also the psychological aspect of floods especially for those who will experience them for the first time. These will surely add to the already fragile mental health of people still reeling from the effects of the COVID-19 pandemic.
As I write, the Marikina River has breached and many areas of Metro Manila and surrounding provinces of Bulacan, Rizal, Laguna and Cavite are flooded. The floods are now being mentioned along with those brought about by Ondoy (Ketsana) in 2009.
Here are some photos from the internet being shared by various social media accounts including the official pages of Rappler and Inquirer:

Back in Tagaytay
It’s been a while since I’ve been to Tagaytay. I think the last time was before the pandemic and with family. There used to be a time when we went there at least every month not counting the seminars and workshops we attended there. It was an easy drive from our home in Antipolo to Tagaytay via C6, SLEX and the Sta. Rosa-Tagaytay Road. We had our favorite stopovers with breakfasts usually at the Paseo de Sta. Rosa. Later, as Tagaytay became more crowded and congested, the trips became fewer. Of course, our schedules also became busier but then it wasn’t like we looked forward to the traffic and the crowded attractions there. I’m doing a project there now with my team at the office and that means I get to go there for work. Since we’ll be there anyway, we could have some side trips to eat some good meals (bulalo!) and maybe take some photos of Taal volcano.
The fog was a quick reminder of the Tagaytay of old that we frequented before. But what we noticed was that it wasn’t cool. It was still somewhat warm if there was no breeze or wind blowing. This was certainly not smog as you can smell the pollution if it was. We even joked that it probably wasn’t because of the volcano as the smell of sulphur would probably be strong. We were in Tagaytay during the weekdays so there were fewer people and traffic. We were told that it was worse on weekends. That was to be expected. And with CALAX, Tagaytay became more accessible to visitors. I will write about the developments there in the next post. I feel there’s just too many buildings and the intense development has made Tagaytay less attractive. I have similar memories and feelings about Baguio but that’s another story to tell or write about.

Extreme turbulence during air travel
Transport-related news last week included a report about a Singapore Airlines B777 jet flying to London from Singapore that had to make an emergency landing in Bangkok due to extreme turbulence experienced. Many people were seriously injured when the plane suddenly ascended (“tilted up” as some news reports state) and then abruptly descended, resulting in people being tossed up and hitting the compartments above their seats. Obviously, these passengers were not wearing their seatbelts at the time. Otherwise, they would have been restrained to their seats. It is likely that the turbulence was not anticipated by the pilot as they usually advise passengers to put on their seat belts if turbulence was expected at any time during a flight.
The incident raises concerns about extreme and sudden turbulence occurring during flights. I guess this may happen anytime and aircraft instruments may not be able to tell the crew about an impending incident like this. Will such an incident have a significant impact on air travel? Perhaps not if these incidents remain rare. There should be records and monitoring of factors or elements leading to such incidents in order to establish the likelihood of these happening. Incident records will also show if there is an increasing frequency as well as the number of people killed and injured. Such information would be vital as more people use aviation for travel and there are more aircraft activity around the world.
As a precaution, it is good practice not to remove your seatbelt while seated in flight. If it’s tight, then loosen it. At least you have some restraint in case of incidents where the aircraft encounters sudden turbulence.
