Usage

This sub-box generates a meteorological information box specifically targeted towards winter storms. When available, this box will change the header to reflect a winter storm category (such as a category provided by the Regional Snowfall Index). Otherwise, it will show a generic "Winter storm" header.

The winter storm category may be supplied using |category=. In the event that this storm has an RSI value, the |RSI= parameter can instead be used, and will automatically adjust the box to use imperial units instead of metric. The |basin= parameter can also be used to change this behavior; set it to atl or epac to switch the default units. To avoid units entirely, you may choose to pass text into the related values (e.g. pass {{convert|100|in|cm|abbr=on}}|maximum-rain= or |maximum-snow=), but this makes later maintenance difficult, and is not advised.

This subbox relies on the meta-template Template:Infobox weather event/meteorology.

{{Infobox weather event/Winter storm
| winds = 112
| lowest-temperature = -45
| maximum-snow = 17
}}

{{Infobox weather event/Winter storm
| RSI = 6.78
| winds = 87
| lowest-temperature = -23
| maximum-rain = 56
| maximum-snow = 12
}}

TemplateData

A subbox for displaying meteorological information for a storm. Should be used adjacent to an 'Infobox weather event' template, and before an 'Infobox weather event/Footer' template.

Template parameters[Edit template data]
This template prefers block formatting of parameters.
Parameter		Description	Type	Status
Child display?	`child`	Whether this is a child box or not. Use `yes`, unless you're using this box standalone. Default yes Example yes	Boolean	optional
Body style	`bodystyle`	Custom CSS for the box Default border-collapse: collapse	String	optional
Storm category	`category`	The storm category. This populates the header color and name automatically.	String	suggested
Basin	`basin`	Basin of the storm. Controls the name of the category, if the category supports basin-specific names. Suggested values `atl` `epac` `satl` `wpac`	String	optional
Header text	`header`	Header text to show. Overrides category name if provided.	Content	optional
Header style	`header-style`	Controls the style of the subbox header. This header usually includes the category of the storm or the storm type, if a category is not applicable. Default font-size: 100%; background-color: #{{Storm colour\|{{{category\|}}}}}	String	optional
No header?	`no-header`	Disables the header row Default no Example yes	Boolean	optional
Subheader text	`subheader`	Subheader text to show. Overrides interval, scale, and agency, if provided.	Content	optional
Measurement interval	`interval`	The measurement interval used by the agency. e.g. JMA uses 10-minute, JTWC uses 1-minute. Example 1	Number	suggested
Post-interval text	`post-interval` `postinterval`	Text to add after "N-minute sustained". A space is automatically provided.	String	optional
Agency	`agency`	Agency issuing the meteorological data. If the agency uses multiple scales, or uses a scale that is used by multiple agencies, consider also supplying "scale". Example [[National Weather Service\|NWS]]	Content	suggested
Scale	`scale`	Scale used to quantify the meteorological data. If the scale is used by multiple agencies, consider supplying "agency". Example [[Saffir–Simpson scale\|SSHWS]]	Content	suggested
Maximum sustained winds	`winds`	The maximum sustained winds of a given storm. Not to be confused with maximum wind gusts (provided with "gusts"). Supply value in knots. Example 124	Number	suggested
Maximum winds prefix	`winds-prefix`	Prefix for the maximum sustained winds. Use this to add approximation symbols, such as '~', '<', or '>'. Example ~	String	optional
Maximum winds suffix	`winds-suffix`	Suffix for the maximum sustained winds. Use this to add references, footnotes, or other content.	Content	optional
Maximum wind gust	`gusts`	The maximum wind gust of a given storm. Not to be confused with maximum sustained winds (provided with "winds"). Supply value in knots. Example 164	Number	suggested
Maximum gusts prefix	`gusts-prefix`	Prefix for the maximum wind gusts. Use this to add approximation symbols, such as '~', '<', or '>'. Example ~	String	optional
Maximum gusts suffix	`gusts-suffix`	Suffix for the maximum wind gusts. Use this to add references, footnotes, or other content.	Content	optional
Beaufort scale	`beaufort-scale` `beaufort scale`	The maximum sustained winds on the Beaufort scale. Rarely used except for historical storms; consider using "winds" instead.	Number	optional
Lowest pressure	`pressure`	Lowest pressure, usually measured near the storm's center. Supply value in hectopascals/millibars (hPa/mbar). Example 975	Number	suggested
Lowest pressure prefix	`pressure-prefix`	Prefix for the pressure. Use this to add approximation symbols, such as '~', '<', or '>'. Example ~	String	optional
Lowest pressure suffix	`pressure-suffix`	Suffix for the lowest pressure. Use this to add references, footnotes, or other content.	Content	optional
Lowest temperature	`lowest-temperature` `lowest temperature`	Lowest temperature. Supply value in Fahrenheit when "basin" is "atl" or "epac". Otherwise, supply the value in Celcius. Example 13	Number	suggested
Lowest temperature prefix	`temperature-prefix`	Prefix for the temperature. Use this to add approximation symbols, such as '~', '<', or '>'. Example ~	String	optional
Lowest temperature suffix	`temperature-suffix`	Suffix for the lowest recorded temperature. Use this to add references, footnotes, or other content.	Content	optional
Largest hail	`largest-hail` `largest hail`	Largest recorded size of hail. Supply value in inches when "basin" is "atl" or "epac". Otherwise, supply the value in centimeters. Example 12	Number	optional
Largest hail suffix	`largest-hail-suffix`	Suffix for the largest hail recorded. Use this to add references, footnotes, or other content.	Content	optional
Maximum rainfall	`maximum-rain` `maximum rain`	Maximum recorded rainfall. Supply value in inches when "basin" is "atl" or "epac". Otherwise, supply the value in centimeters. Example 42	Number	optional
Maximum rainfall suffix	`maximum-rain-suffix`	Suffix for the maximum recorded rainfall. Use this to add references, footnotes, or other content.	Content	optional
Maximum snow or ice accretion	`maximum-snow` `maximum snow`	Maximum height of accumulated snow or ice accretion. Supply value in inches when "basin" is "atl" or "epac". Otherwise, supply the value in centimeters.	Content	optional
Maximum snow accumulation or ice accretion suffix	`maximum-snow-suffix`	Suffix for the maximum recorded snow accumulation or ice accretion. Use this to add references, footnotes, or other content.	Unknown	optional
Regional Snowfall Index	`RSI`	The Regional Snowfall Index value of the storm. Since the RSI only exists in North America, this automatically switches the basin and thus switches the primary units used. Be sure to input the value, not the category (i.e., not 0–5).	Number	suggested
Storm type	`type`	The winter storm type. Changes the header or category suffix, if a category is available. Most commonly used by other subboxes; avoid supplying this parameter directly to avoid redundancy.	Content	optional
