class pyiem.nws.product.TextProduct(text, utcnow=None, ugc_provider=None, nwsli_provider=None, parse_segments=True)[source]#

Bases: WMOProduct

class representing a NWS Text Product

suv_iter()[source]#: Yield [(segment, ugcs, vtec)] combos found in product.

is_resent()[source]#: Check to see if this product is a …RESENT product

is_correction()[source]#

Is this product a correction?

Sadly, this is not as easy as it should be. It turns out that some products do not have a proper correction mechanism, so offices will just brute force in a note into the MND header. So we have to do some further checking…

Returns:: Is this product a correction?

parse_attn_wfo()[source]#: Figure out which WFOs this product is seeking attention

get_channels()[source]#: Return a list of channels

Return a tuple of jabber messages [(plain, html, xtra_dict)]

Parameters:: uri (str) – the base URI to use to construct links
Returns:: [(str, str, dict)]

get_signature()[source]#

Attempt to glean the free form text that is a signature.

Return type:: str | None

parse_segments()[source]#: Split the product by its $$

get_affected_wfos()[source]#: Based on the ugc_provider, figure out which WFOs are impacted by this product
