What to do at each level
| Level | Flooding | Landslide | Wildfire | Falling trees | Heatwave |
|---|---|---|---|---|---|
| Low | Normal day. Nothing expected. | Normal day. Nothing expected. | Normal day. Nothing expected. | Normal day. Nothing expected. | Normal day. Nothing expected. |
| Moderate | Check the worst time of the rain and leave before or after it. Large puddles and slow traffic in the spots that often flood. | If you live on a hillside, look for new cracks in walls and on the floor. The soil starts to get soaked. Earth may fall from slopes. | Do not burn trash or leaves. Do not throw cigarette butts into vegetation. Dry brush catches fire easily. There may be smoke on vacant lots and roadsides. | Do not park under trees. Branches may fall on tree-lined streets. | Drink water throughout the day, even if not thirsty. Avoid strong sun between 10 am and 4 pm. Hotter than normal. Older people, babies and people with heart or kidney disease feel it more. |
| High | Leave well ahead of time, or stay where you are until the rain passes. Park your car on high ground, away from low streets. Flooded streets in several neighborhoods, traffic at a standstill, buses and subway delayed, cars may get stuck. | If you live on a hillside, leave at the first sign: a new crack, a door that sticks, a cracking sound or muddy water. Avoid mountain roads. Landslides are possible on hillsides. Streets and mountain roads may be blocked. | Do not burn anything. If you see fire or smoke, call 193. Fires in woods and vacant lots. Smoke in the air and poor visibility on roads. | Do not stand or park under trees. Keep your phone charged and have a flashlight at home. Trees may fall in several neighborhoods, block streets and bring down power lines. Power outages are possible. | Call or visit older people and neighbors who live alone. Spend at least 2 to 3 hours a day somewhere cool and leave exercise for early morning or late afternoon. Dangerous heat for several days. Risk of dehydration and of worsening heart, blood pressure and kidney conditions, especially in older people. |
| Very high | Avoid going out that day. If you live near a stream, move to high ground before the rain. Widespread flooding, streets closed for hours, water may get into homes and shops, danger to life near streams. | If you live on a hillside, move to a safe place before the rain. Avoid mountain roads that day. Landslides are likely. Hillside homes may be hit, with danger to life. | If you live near woods, clear dry leaves and trash around the house and agree on an escape route. Close the windows because of the smoke and drink plenty of water. Fire spreads fast and is hard to control. Smoke harms health, and homes near woods may be hit. | Stay home during the windstorm, away from windows. Never touch a fallen wire: call the power company or 193. Many trees and poles may fall. Blocked streets, hours without power and danger to life for anyone outdoors. | Dizziness, confusion, fainting or hot, dry skin: call 192 (SAMU). Never leave a child or pet inside a car. Above 40 °C a fan is not enough: go somewhere with air conditioning. Extreme heat that can kill. Clinics and hospitals get busier. |

Questions we hear about i4sea Weather Index
A weather risk index from 0 to 100. It shows the chance that the weather in the next 24 hours causes flooding, landslides, wildfire, falling trees or a heatwave in 421 Brazilian cities, and what to do. It combines the i4sea weather forecast with what makes each neighborhood more exposed, such as the terrain, the trees and the places that have flooded before.
Flooding: heavy rain that can fill streets. Landslide: accumulated rain that can bring slopes down. Wildfire: dry, hot and windy weather that helps fire spread. Falling trees: wind gusts that can knock down trees and poles. Heatwave: several days of unusual heat for the city, most dangerous for older people and children.
The index covers 421 cities: all state capitals, the cities with more than 100,000 residents and cities that matter for each state's economy. Use the search to find yours.
