The National Administration of Meteorology (ANM) has issued a nationwide yellow code warning for storms, effective from 10:00 on July 2 until 10:00 on July 3. According to ANM, the weather system will bring heavy rain, frequent lightning, and wind gusts between 50 and 70 km/h, with isolated peaks exceeding 80 km/h, alongside small hail (1–2 cm).
Why is Romania experiencing simultaneous storms and heatwaves?
Romania is currently facing a dual meteorological threat. While the entire country is under a yellow code for atmospheric instability, specific regions—Maramureș, Transylvania, and northern and central Moldova—are simultaneously battling a persistent heatwave. According to ANM, this combination creates high thermal discomfort, as the temperature-humidity index (ITU) is expected to reach or exceed the critical threshold of 80 units.

In these heat-affected regions, maximum temperatures are forecasted to range between 31 and 34 degrees Celsius. This contrast between extreme heat and sudden, violent storms is a characteristic of volatile summer patterns where high humidity and heat fuel the development of severe convective cells.
What should residents of Bucharest expect?
Bucharest is under a specific forecast valid from 10:00 on July 2 to 10:00 on July 3. ANM reports that the weather will remain generally unstable, with a higher probability of storms during the afternoon and night. Residents can expect rain totals between 15 and 25 l/mp, lightning, and wind gusts reaching 50 to 60 km/h.
The capital’s temperature is expected to peak at 29–30 degrees Celsius and drop to a minimum of 17–18 degrees. The ANM explicitly warns of hail conditions in the city, aligning with the broader national yellow code for small hail and significant rainfall.
Comparing the regional impacts: Heat vs. Storms
The current weather event shows a clear divide in how different Romanian regions are affected. While the storm risk is universal, the heat stress is localized.
| Region | Primary Threat | Key Metric |
|---|---|---|
| National (All) | Storms/Hail | Wind gusts up to 80+ km/h |
| Maramureș/Transylvania/Moldova | Heatwave | ITU > 80 units |
| Bucharest | Instability | Rain 15–25 l/mp |
How to prepare for rapid weather shifts
When a yellow code is active, the transition from a heatwave to a storm can happen in minutes. According to the data provided by ANM, rainfall can accumulate up to 30–40 l/mp in restricted areas over short intervals of 1 to 3 hours. This volume of water often leads to localized flash flooding in urban drainage systems.
Frequently Asked Questions
What does a “Yellow Code” mean in Romania?
It is a meteorological warning indicating that the weather may be dangerous, but it is not expected to cause widespread disruption. However, it requires caution and monitoring of official updates from ANM.
How much rain is expected during these storms?
ANM forecasts general accumulations of 15–25 l/mp, with some restricted areas seeing over 30–40 l/mp in short windows of 1 to 3 hours.
Which regions are most affected by the heatwave?
The heatwave persists specifically in Maramureș, Transylvania, and the northern and central parts of Moldova.
