A Pilot Report (PIREP) is a report of weather conditions encountered by an aircraft during a flight. This information is usually relayed by radio to the nearest ground station.

A weather report is a statement of the actual weather conditions observed at a specific time at a specific site.

E-19, Report on River Gage Station
In hydrologic terms, a report to be completed every 5 years providing a complete history of a river station and all gages that have been used for public forecasts since the establishment of the station.

PILOT REPORT A report of in-flight weather by an aircraft pilot or crew member. Often referred to as a PIREP.
Record Report This nonroutine narrative product is issued by the National Weather Service to report meteorological and hydrological events that equal or exceed existing records.
Reporters Dan Hartzell, Joe Nixon, and Hal Markovitz contributed to this article.

Other reports try to tell us "the sky is falling" and the end of the world is near. But, the weather is the weather, an ever-changing part of the earth's natural environment.

On a buoy report, the ten-minute average wind direction measurements in degrees clockwise from true North.Direct Flood DamageIn hydrologic terms, the damage done to property, structures, goods, etc.
SYNOPtic report. Similar to a METAR, but gives additional details of the weather at a site. SYNOP's are only reported at most every three hours.

Automated Event-Reporting Gage: River stage gages, IFLOWS pressure transducer type gages can be programmed to report if water surface rises or falls by a predetermined amount. See Tipping Bucket Rain Gage.
A trace of rain is reported by rainfall observers when a little precipitation can be seen in the rain gauge, but there is less than 0.1 mm in total.
LSR- Local Storm Report

Blowing sandSand particles picked up from the surface of the earth by the wind to moderate heights above the ground, reducing the reported horizontal visibility to less than seven statute miles.
In observing, sand is reported when particles of sand are raised to sufficient height that reduces visibility. It is reported as "SA" in an observation and on the METAR. SANDSTORM A strong wind carrying sand particles through the air.
GDROn a buoy report, direction, in degrees clockwise from true North, of the GSP, reported at the last hourly 10-minute segment.
SAWRS Supplemental Aviation Weather Reporting Station. A facility where weather observations are taken, prepared, and transmitted by a local operator under federal government supervision. SCADA Supervisory Control and Data Acquisition.
Data Quality Assessment Report (DQAR)An assessment report issued by the Data Quality Office and/or instrument mentors based on a data quality inspection.
Often a severe weather season will come and go without a single F5 tornado reported. However, about 80% of all tornadoes deaths are the result of the F3, F4 and F5 tornadoes. These storms are much less common, but much more dangerous.
There is now one operating at the MSP airport, reporting air temperature, cloud ceiling, visibility, dew point, and wind among other things. Forecasters use the frequent ASOS reports to refine and update forecasts.
weather observing procedure, a thunderstorm is reported whenever thunder is heard at the station; it is reported on regularly scheduled observations if thunder is heard within 15 minutes preceding the observation.
These are mainly F0 and F1, with only a few F3's reported, and no F4's or F5's. The Netherlands is second with 35 per year. There are probably as many as 700 tornadoes a year in all of Europe, though only some 330 are reported.

Daily Climatological Report As the name indicates, this climatological product is issued daily by each National Weather Service office.
The cold front associated with these storms can be studies for thunderstorm and tornado development, while the backside of a winter storm can be chased so a snow storm report can be done.
A system of estimating and reporting wind speeds. It is based on the Beaufort Force or Number, which is composed of the wind speed, a descriptive term, and the visible effects upon land objects and/or sea surfaces.
ALERT- Automated Local Event Reporting in Real Time. Network of automatic raingauges that transmit via VHF radio link when precipitation occurs.
