Severe Weather

Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. Types of severe weather phenomena vary, depending on the latitude, altitude, topography, and atmospheric conditions.

Severe weather warnings or alerts which may lead to disruption. Severe weather alerts include storms, extreme temperature, flood, etc. For example, a for southeastern Webster Parish in northwestern Louisiana alerts people that a severe thunderstorm along with damage in the nearby area is likely to occur in the upcoming hour.

Severe weather storm events can change over time. Events like hurricanes, tornados and other storms move across different locations and change in strength as time goes on. This can be reflected by different warning events in our system. It’s possible to have multiple warnings about the same weather condition:

  • The bad weather condition lasts longer than expected. For example, a in east Tennessee that the potential threat may last until 3 PM. Another that indicates additional rainfall may occur on the day and the following day, and the road closures will remain in place.

  • Multiple areas can be affected. For example, On March 14th, several regions in South Dakota have issued blizzard warnings, such as , , , and .

  • Warnings may be issued hours or days in advance. The event (warning) state will change to cancelled if the potential threat no longer exist. For example the storm didn't hit as expected. Past events with an active state mean the event has happened.

  • Severe weather data is updated in near real time with event details being refreshed on average every 15 mins.

  • PredictHQ provides historical severe weather data that can be used for purposes like training a demand forecasting model.

LABELS

This category is classified into three buckets with the following labels used to identify the type of severe weather.

  1. Storm

    storm, tornado, blizzard, dust, hurricane, cyclone, rain, wind, typhoon, sand

  2. Extreme Temperature

    cold-wave, heat-wave, air-quality, snow

  3. Flood

Ranking

PHQ Rank

Severe weather events have PHQ Rank available.

CAP features evaluate the event from three aspects: urgency, severity and certainty. For example, a warning about an extreme (severity) weather condition that is likely (certainty) to happen immediately (urgency) will have a higher rank. The table below shows the weight of each value of severity, urgency, and certainty when calculating the PHQ Rank.

For example, An event with an urgency of immediate (15), a severity of severe (36), and a certainty of observed (35) would have a PHQ Rank of 86.

Local Rank

Severe weather events have no Local Rank available as they impact an entire area instead of a specific point.

PHQ Attendance

Severe weather events have no PHQ Attendance available as the rank/impact only reflects its influence on an area, rather than a specific amount of attendees at a specific location.

Disasters

Disaster events are major adverse events resulting from natural processes of the Earth, for example, earthquakes, volcanoes, tsunamis, etc. The reduction and/or limitation of social activities that are forced by COVID-19 pandemic is also classified under the disaster category.

These events tend to be high-impact disasters noticed at a regional or country level.

Labels

This category is classified into three buckets with the following labels used to identify the type of disasters.

  1. Hydrological_geophysical

    earthquake, avalanche, landslide, volcano, tsunami, ashfall

    1. Note: Earthquake coverage typically includes magnitude 4 and above earthquakes.

  2. Climatological

    fire, wildfire, drought

    There are seven government mandated events in the US on a state level. These events indicate if a government body has mandated that the activity stays open or closed during a specified period of time.

The PHQ Rank indicates the severity of the bad weather, with using the data. CAP is an international non-proprietary digital message format for all-hazard emergency events. The benefit of using CAP is there is consistency in how it is implemented in different countries, making it easier to use. CAP alerts can be geographically targeted to a defined warning area.

The government mandated stay-at-home orders during the COVID-19 pandemic that restrict or reduce social activities on different levels. Lockdown events have health, lockdown and disaster labels. For example, , .

The natural disaster events consider information, number of injured, deaths, evacuated, etc.
