This product, the Tropical Weather Outlook, briefly describes
significant areas of disturbed weather and their potential for
tropical cyclone formation during the next seven days. The issuance
times of this product are 5 AM, 11 AM, 5 PM, and 11 PM PDT. After
the change to standard time in November, the issuance times are
4 AM, 10 AM, 4 PM, and 10 PM PST.

A Special Tropical Weather Outlook will be issued to provide
updates, as necessary, in between the regularly scheduled issuances
of the Tropical Weather Outlook. Special Tropical Weather Outlooks
will be issued under the same WMO and AWIPS headers as the regular
Tropical Weather Outlooks.

A standard package of products, consisting of the tropical cyclone
public advisory, the forecast/advisory, the cyclone discussion, and
a wind speed probability product, is issued every six hours for all
ongoing tropical cyclones. In addition, a special advisory package
may be issued at any time to advise of significant unexpected
changes or to modify watches or warnings.

NHC has the option to issue advisories, watches, and warnings for
disturbances that are not yet a tropical cyclone, but which pose
the threat of bringing tropical storm or hurricane conditions to
land areas within 72 hours. For these land-threatening "potential
tropical cyclones", NHC will issue the full suite of advisory and
watch/warning products. Potential tropical cyclones share the
naming conventions currently in place for tropical depressions,
being numbered from a single list (e.g., "One-E", "Two-E",
"Three-E", etc.).

The Tropical Cyclone Update is a brief statement to inform of
significant changes in a tropical cyclone, to post or cancel
watches or warnings, or to provide hourly position updates between
intermediate advisories when the storm center is easily followed by
radar. The Tropical Cyclone Update is also used in lieu of or to
precede the issuance of a special advisory package. Tropical
Cyclone Updates, which can be issued at any time, can be found
under WMO header WTPZ61-65 KNHC, and under AWIPS header MIATCUEP1-5.

graphical products can be found at

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1137 AM CDT Thu May 15 2025 Valid 151700Z - 161200Z Cooler temperatures and lighter boundary layer winds will mitigate fire weather concerns across southeastern Arizona today, necessitating a slight pullback in Elevated highlights. Stronger mid-level winds and efficient mixing will continue to support an elevated fire weather threat across southern New Mexico into far west Texas. Downslope/leeward enhancement of surface winds should also occur across the High Plains of northeastern New Mexico. ..Williams.. 05/15/2025 .PREV DISCUSSION... /ISSUED 0104 AM CDT Thu May 15 2025/ ...Synopsis... An upper trough will quickly move eastward over the central US with accompanying strong mid-level flow. A deepening lee cyclone will intensify further as it move into the Upper Midwest tonight. As the low deepens, a Pacific cold front and tailing dryline will move quickly through the Rockies, into the Plains and Midwest States. Cooler temperatures, gusty westerly winds and some precipitation are possible along and behind the front through tonight. Elevated fire-weather conditions are possible over parts of the southern Plains and Southwest. ...Southwest... Persistent westerly flow will continue across the Southwest today and tonight as a weak pacific front moves over the Rockies. This will support another day of dry and windy conditions across parts of eastern AZ and southern NM. Despite somewhat cooler temperatures behind the front, downsloping and deep vertical mixing will support RH below 20% and winds of 15-20% amidst dry fuels. Widespread elevated to locally critical conditions are expected. Some fire-weather risk may also extend into West TX behind an eastward mixing dryline. However, winds here may be somewhat weaker despite very warm surface temperatures and lower humidity. Locally elevated conditions are possible within drying fuels. ...Central plains and Midwest... Gusty westerly winds are possible behind the advancing cold front from parts of the central Plains into western IA and MO this afternoon. While gusts may reach 20-25 mph, RH values are not expected to be critical with cooler temperatures. Additionally, recent wetting rainfall may temporarily limit available fuels. This suggests any fire-weather concerns will be localized and short lived. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1137 AM CDT Thu May 15 2025 Valid 151700Z - 161200Z Cooler temperatures and lighter boundary layer winds will mitigate fire weather concerns across southeastern Arizona today, necessitating a slight pullback in Elevated highlights. Stronger mid-level winds and efficient mixing will continue to support an elevated fire weather threat across southern New Mexico into far west Texas. Downslope/leeward enhancement of surface winds should also occur across the High Plains of northeastern New Mexico. ..Williams.. 05/15/2025 .PREV DISCUSSION... /ISSUED 0104 AM CDT Thu May 15 2025/ ...Synopsis... An upper trough will quickly move eastward over the central US with accompanying strong mid-level flow. A deepening lee cyclone will intensify further as it move into the Upper Midwest tonight. As the low deepens, a Pacific cold front and tailing dryline will move quickly through the Rockies, into the Plains and Midwest States. Cooler temperatures, gusty westerly winds and some precipitation are possible along and behind the front through tonight. Elevated fire-weather conditions are possible over parts of the southern Plains and Southwest. ...Southwest... Persistent westerly flow will continue across the Southwest today and tonight as a weak pacific front moves over the Rockies. This will support another day of dry and windy conditions across parts of eastern AZ and southern NM. Despite somewhat cooler temperatures behind the front, downsloping and deep vertical mixing will support RH below 20% and winds of 15-20% amidst dry fuels. Widespread elevated to locally critical conditions are expected. Some fire-weather risk may also extend into West TX behind an eastward mixing dryline. However, winds here may be somewhat weaker despite very warm surface temperatures and lower humidity. Locally elevated conditions are possible within drying fuels. ...Central plains and Midwest... Gusty westerly winds are possible behind the advancing cold front from parts of the central Plains into western IA and MO this afternoon. While gusts may reach 20-25 mph, RH values are not expected to be critical with cooler temperatures. Additionally, recent wetting rainfall may temporarily limit available fuels. This suggests any fire-weather concerns will be localized and short lived. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
