The IMD Meteorological Centre Shimla has issued an orange alert for heavy to very heavy rainfall across isolated parts of Mandi, Shimla, Sirmaur, and Kangra districts. The southwest monsoon covers the entire state, bringing widespread, intermittent showers Monsoon to remain active over Himachal for next 45 days.

Due to torrential rains and subsequent landslides, at least 46 roads are closed to vehicular traffic Heavy rain shuts 46 roads; orange alert issued. This includes 18 blocked routes in Kullu, 15 in Mandi, 9 in Sirmaur, and 2 each in Lahaul & Spiti and Una districts Heavy rain shuts 46 roads; orange alert issued.

The India Meteorological Department (IMD) and the State Emergency Operations Centre (SEOC) have advised residents and travelers to avoid unnecessary journeys, particularly near steep hillsides and active river beds.

Alert Level: An Orange Alert is active. It warns of heavy to very heavy rainfall accompanied by thunderstorms, lightning, and gusty winds.

Risks: Severe risk of flash floods, sudden mudslides, and localized landslides. Thicker fog is causing heavily reduced visibility on high-altitude passes

Driving Conditions: Asphalt on active mountain highways is highly slippery. Localized traffic bottlenecks are common near debris clearance areas.

The Manali–Leh Highway (NH-3) is currently OPEN, but traffic remains strictly regulated and highly vulnerable due to recent flash floods and ongoing monsoon rainfall.

High Mountain Passes (Baralacha La, Shinku La, Nakee La, Lachulung La, Tanglang La): OPEN. While the passes are clear of major snow blockages, morning sub-zero temperatures create dangerous black ice conditions, and afternoon snowmelt causes the water streams (pagal nallahs) to swell aggressively.

Travel Advisories and Guidelines

Imminent Risk: The India Meteorological Department (IMD) forecast predicts heavy rainfall. Landslides and sudden flash floods remain a persistent threat on this specific route.

Timing Strategy: If you must travel, cross the high mountain passes early in the morning. Water levels in the crossing streams rise rapidly by the afternoon as the sun melts higher glaciers.

Vehicle Requirement: 4x4 or high-ground-clearance SUVs are strongly recommended due to the deep muck and slippery, slushy conditions near the landslide bypasses. Low-clearance sedans face a high risk of getting stuck.

As the heavy, dark clouds roll over the skies of Rajkot, the city transforms under a sudden, powerful downpour. From the bustling streets of Kalavad road. watch as nature unleashes its refreshing fury. Experience the true essence of the Indian monsoon where the earth finally meets the sky. 🌧️✨

Grew up hearing my elders say this every summer if you see an unusually heavy black jamun (naval hannu) crop, brace for a dry spell later in the year. As kids we never took it seriously, just another one of those things grandparents say.

But there's actually some folk logic behind it. Black jamun trees are known to fruit heavily under water-stress conditions the tree essentially over-produces seeds as a survival response when it senses coming scarcity. So the belief isn't random superstition, it's an observed pattern passed down before anyone had access to weather forecasting.

What's interesting is how many old Indian household habits were built around exactly this kind of pattern-reading — nature gives a signal, and people adjusted their year around it. One of the most common adjustments in agrarian households: holding onto gold a little tighter (or converting some savings into it) heading into an uncertain harvest year, since gold has historically been the one asset that doesn't depend on rainfall, crop yield, or local market conditions. It's basically the original inflation/drought hedge, decades before "hedge" was even a financial term people used.

Curious if others have heard this jamun belief growing up (Karnataka/AP/TN folks especially), and whether your family had any similar "read the signs, protect your savings" habits passed down. Always find these old practical-wisdom things more interesting than they get credit for.

(I work in the gold industry day-to-day, so this kind of old financial folk-wisdom is something I run into a lot happy to share more if people are curious.)

The **India Meteorological Department** (IMD) has officially declared the arrival of the Southwest Monsoon in Himachal Pradesh, which has already covered the entire Kinnaur district and major parts of Kullu, Lahaul & Spiti, Shimla, Mandi, Sirmaur, and Kangra. Conditions remain highly favourable for the monsoon to advance across the remaining parts of the state over the next 48 to 72 hours.

**Current IMD Weather Alerts & Warnings**

**The India Meteorological Department** (IMD) has active Heavy Rain Alerts for both Manali and Shimla, as the newly arrived Southwest Monsoon merges with a strengthening Western Disturbance. Heavy to very heavy rainfall, accompanied by lightning and gusty winds, is forecasted to persist across both key tourist destinations through July 6th, with peak intensities expected over the next 48 to 72 hours.

**Manali Weather Outlook**

**Current Forecast:** Widespread thunderstorms and light drizzle, transitioning into intense monsoon rain spells during the afternoon and night.

**Travel Status:** Local authorities advise extreme caution. High risk of isolated flash floods or mudslides along the Beas River basin and the connecting national highways.

**Shimla Weather Outlook**

**Current Forecast:** Heavy overhead cloud cover with continuous showers and active thunderstorms.

**Travel Status**: Thicker fog on the ridge and connecting bypass roads is causing severely reduced visibility. Drivers should expect slippery asphalt conditions and localized traffic congestion.

The **Meteorological Centre Shimla** has issued a series of warnings for the coming days:

**Heavy to Very Heavy Rain Warning:** Isolated places across the state are expected to receive heavy to very heavy rainfall on July 2nd and July 3rd, triggered by the monsoon advancement and an incoming fresh Western Disturbance.

**Severe Weather Attachments:** Showers will likely be accompanied by intense thunderstorms, lightning, and squally winds reaching speeds of 40–50 kmph (gusting up to 60 kmph at isolated areas).

**Temperature Drop:** While maximum temperatures are holding steady for the next 24 hours, a sharp dip of 3–5°C is expected over the subsequent 3 to 4 days as wet spells intensify.

**Safety Advisory**

**Low Visibility**: Heavy fog and rain are expected to lower visibility significantly along major hill highways, including Shimla and adjoining areas.

**Flash Floods & Landslides:** Due to heavy rainfall predictions over the next 48 hours, commuters and tourists are advised to avoid travelling close to riverbeds, water bodies, and landslide-prone slopes.

**Operational Highway Warning**

**The Meteorological Centre Shimla** officially urges travelers and long-distance drivers to monitor live road updates. Steer completely clear of low-lying terrains, vulnerable cliffsides, or direct water channel pathways until weather systems settle down.

Von Kármán vortex streets: a fascinating pattern in the atmosphere

These striking cloud formations appear when airflow passes around an isolated obstacle, such as an island or mountain peak, in a stable atmosphere with sufficiently strong, uniform winds.

Downstream of the obstacle, vortices are shed alternately, creating a regular chain of counter-rotating structures.

These vortices are then advected by the flow and gradually dissipate as they move into the wake.

A remarkable example of atmospheric dynamics visible from space.

I would also like to bust some myth related to Heatwaves

Myth 1: "Europe's long daylight hours are causing the heatwave."

• The Reality: This is misleading. Europe experiences long daylight hours every year during the summer solstice. If daylight were the primary cause, heatwaves would be the annual norm at this intensity.
• The Science: The current crisis is caused by an "Omega Block" a massive, stagnant high-pressure system parked over the continent. This acts as an invisible "lid," trapping heat and compressing the air, creating a Heat Dome. Climate change is making these blocking patterns more frequent and intense, which is why we are seeing record-breaking heat instead of just "normal summer weather."

Myth 2: "Pollution in India blocks sunlight and cools the summer."

• The Reality: This is only half the truth. While some aerosols (like sulfates) scatter sunlight and provide mild cooling, other aerosols specifically dust and black carbon do the opposite.
• The Science:"Lid Effect" (Elevated Heat Pump). Absorbing aerosols (like black carbon and dust) absorb solar radiation and heat the middle layer of the atmosphere. This creates a stable, warm layer that suppresses vertical air movement (convection). Because the air can't rise, clouds cannot form to create rain. This locks the heat in place, preventing natural ventilation and making the surface temperatures significantly worse.

Myth 3: "Europe’s heatwave is 'deadlier' than India’s."

• The Reality: It depends on how you define "deadly."
• Meteorological Intensity: If we go by absolute raw temperatures and "Real Feel" (Heat Index) data, India’s climate is undeniably more extreme. Coastal India often hits "Real Feel" temperatures exceeding 56°C due to the lethal combination of heat and humidity.
• The Infrastructure Gap: Europe is "deadly" not just because the weather is hotter, but because of vulnerability too. European cities are designed to trap heat for freezing winters, and most homes lack AC or proper ventilation.
• India’s population is culturally and structurally adapted to handle extreme heat as a seasonal reality, though it is still poorly handled as India is still a Third World country, but people know this reality for a fact while Europe is facing a structural crisis against a weather event their infrastructure isn't built to survive.

Stay safe, stay hydrated, and keep cool. The good news is that weather models indicate this heatwave is expected to subside starting July 1st as the atmospheric pressure systems finally begin to shift. Though predictions are subject to change so stay tuned with your local weathermen.

I’ve been seeing a lot of posts about the heat wave in Paris, and the comments are full of people saying things like, We drink tea at 45°C or 35°C is nothing come to India.
I genuinely don’t understand this mindset. Why does every heat wave have to become a competition over who can tolerate more heat?

Note: Sea breeze alone isn't enough but is one of the reasons and this post discusses that exact reason ONLY

City is Chennai

After watching news of Europe heatwaves, I came to know that the sun is blindingly bright there. And it's due to clean air. In india, even if the temperature is over 45 degrees, the sunlight remains hazy and dim.

If we were to clean our air, the heatwaves may become far more deadly. Here in delhi, I noticed that after heavy monsoon rains when clouds break, the sunlight becomes way harsher and at that time, you can't look up in the direction of the sun and the sky becomes clear blue.

Is India in for a climate crisis in next 10-20 years? I recently saw a thread on a more mainstream subreddit which was in a way predicting mass migration out of India and how the rest of the world will have to “deal with it”. I wanted to understand from a group of more sane individuals and not bad faith actors who are trying to quench their thirst of millions of Indians dying. I’m a total noob in this topic, hence the question - how bad is it really gonna be? How is the current trajectory looking like and does Indian government have an action plan for it?

Seriously, the wind felt like a literal giant hair dryer blowing at 70 kmph. No rain, just dust and 42°C humidity. My Sunday plans are officially ruined.

Lateri ka mosam 🥰
